The SUSE Linux Enterprise 15 SP1 RT kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-14835: A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could have used this flaw to increase their privileges on the host (bnc#1150112).

CVE-2019-15216: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver (bnc#1146361).

CVE-2019-15924: fm10k_init_module in drivers/net/ethernet/intel/fm10k/fm10k_main.c had a NULL pointer dereference because there was no -ENOMEM upon an alloc_workqueue failure (bnc#1149612).

CVE-2019-9456: In the Pixel C USB monitor driver there was a possible OOB write due to a missing bounds check. This could have led to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1150025).

CVE-2019-15031: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via an interrupt. To exploit the vulnerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE was misused in arch/powerpc/kernel/process.c (bnc#1149713).

CVE-2019-15030: In the Linux kernel on the powerpc platform, a local user could have read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check (bnc#1149713).

CVE-2019-15920: SMB2_read in fs/cifs/smb2pdu.c had a use-after-free.
(bnc#1149626).

CVE-2019-15921: There was a memory leak issue when idr_alloc() fails in genl_register_family() in net/netlink/genetlink.c (bnc#1149602).

CVE-2018-21008: A use-after-free could have been caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591).

CVE-2019-15919: SMB2_write in fs/cifs/smb2pdu.c had a use-after-free (bnc#1149552).

CVE-2019-15917: There was a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c (bnc#1149539).

CVE-2019-15926: An out-of-bounds access existed in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file drivers/net/wireless/ath/ath6kl/wmi.c (bnc#1149527).

CVE-2019-15927: An out-of-bounds access existed in the function build_audio_procunit in the file sound/usb/mixer.c (bnc#1149522).

CVE-2019-15902: Misuse of the upstream 'x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()' commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped (bnc#1149376).

CVE-2019-15666: There was an out-of-bounds array access in
__xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandled directory validation (bnc#1148394).

CVE-2019-15219: There was a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver (bnc#1146524).

CVE-2019-14814: There was a heap-based buffer overflow in the Marvell wifi chip driver, that allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146512).

CVE-2019-14815: There was a heap-based buffer overflow in the Marvell wifi chip driver, that allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code.
(bsc#1146514)

CVE-2019-14816: There was a heap-based buffer overflow in the Marvell wifi chip driver, that allowed local users to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1146516).

CVE-2019-15220: There was a use-after-free caused by a malicious USB device in the drivers/net/wireless/intersil/p54/p54usb.c driver (bnc#1146526).

CVE-2019-15538: An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS (bnc#1148093).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  - The bnep_sock_ioctl function in     net/bluetooth/bnep/sock.c in the Linux kernel before     2.6.39 does not ensure that a certain device field ends     with a '\0' character, which allows local users to     obtain potentially sensitive information from kernel     stack memory, or cause a denial of service (BUG and     system crash), via a BNEPCONNADD command.
    (CVE-2011-1079)

  - An issue was discovered in fs/gfs2/rgrp.c in the Linux     kernel before 4.8. A use-after-free is caused by the     functions gfs2_clear_rgrpd and read_rindex_entry.
    (CVE-2016-10905)

  - An issue was discovered in     drivers/scsi/aacraid/commctrl.c in the Linux kernel     before 4.13. There is potential exposure of kernel stack     memory because aac_get_hba_info does not initialize the     hbainfo structure. (CVE-2017-18550)

  - An issue was discovered in the Linux kernel before     4.14.11. A double free may be caused by the function     allocate_trace_buffer in the file kernel/trace/trace.c.
    (CVE-2017-18595)

  - Improper invalidation for page table updates by a     virtual guest operating system for multiple Intel(R)     Processors may allow an authenticated user to     potentially enable denial of service of the host system     via local access. (CVE-2018-12207)

  - An issue was discovered in the Linux kernel before 4.20.
    There is a race condition in smp_task_timedout() and     smp_task_done() in drivers/scsi/libsas/sas_expander.c,     leading to a use-after-free. (CVE-2018-20836)

  - An issue was discovered in the Linux kernel before     4.18.7. In create_qp_common in     drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp     was never initialized, resulting in a leak of stack     memory to userspace. (CVE-2018-20855)

  - An issue was discovered in fs/xfs/xfs_super.c in the     Linux kernel before 4.18. A use after free exists,     related to xfs_fs_fill_super failure. (CVE-2018-20976)

  - In the tun subsystem in the Linux kernel before 4.13.14,     dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a     denial of service (NULL pointer dereference and panic)     via an ioctl(TUNSETIFF) call with a dev name containing     a / character. This is similar to CVE-2013-4343.
    (CVE-2018-7191)

  - Insufficient access control in subsystem for Intel (R)     processor graphics in 6th, 7th, 8th and 9th Generation     Intel(R) Core(TM) Processor Families; Intel(R)     Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900     Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100     Processor Families may allow an authenticated user to     potentially enable denial of service via local access.
    (CVE-2019-0154)

  - Insufficient access control in a subsystem for Intel (R)     processor graphics in 6th, 7th, 8th and 9th Generation     Intel(R) Core(TM) Processor Families; Intel(R)     Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900     Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and     E-2200 Processor Families; Intel(R) Graphics Driver for     Windows before 26.20.100.6813 (DCH) or 26.20.100.6812     and before 21.20.x.5077 (aka15.45.5077), i915 Linux     Driver for Intel(R) Processor Graphics before versions     5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may     allow an authenticated user to potentially enable     escalation of privilege via local access.
    (CVE-2019-0155)

  - TSX Asynchronous Abort condition on some CPUs utilizing     speculative execution may allow an authenticated user to     potentially enable information disclosure via a side     channel with local access. (CVE-2019-11135)

  - The Linux kernel before 5.1-rc5 allows page->_refcount     reference count overflow, with resultant use-after-free     issues, if about 140 GiB of RAM exists. This is related     to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h,     kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - The do_hidp_sock_ioctl function in     net/bluetooth/hidp/sock.c in the Linux kernel before     5.0.15 allows a local user to obtain potentially     sensitive information from kernel stack memory via a     HIDPCONNADD command, because a name field may not end     with a '\0' character. (CVE-2019-11884)

  - ** DISPUTED ** An issue was discovered in     drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr,     which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is     handled sufficiently and there is no chance for a NULL     pointer dereference. (CVE-2019-12382)

  - An issue was discovered in the Linux kernel before     5.2.3. There is a use-after-free caused by a malicious     USB device in the drivers/media/usb/dvb-usb/dvb-usb-     init.c driver. (CVE-2019-15213)

  - An issue was discovered in xfs_setattr_nonsize in     fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS     partially wedges when a chgrp fails on account of being     out of disk quota. xfs_setattr_nonsize is failing to     unlock the ILOCK after the xfs_qm_vop_chown_reserve call     fails. This is primarily a local DoS attack vector, but     it might result as well in remote DoS if the XFS     filesystem is exported for instance via NFS.
    (CVE-2019-15538)

  - In the Linux kernel before 5.1.13, there is a memory     leak in drivers/scsi/libsas/sas_expander.c when SAS     expander discovery fails. This will cause a BUG and     denial of service. (CVE-2019-15807)

  - An issue was discovered in the Linux kernel before     5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which     will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in the Linux kernel before     5.0.4. The 9p filesystem did not protect i_size_write()     properly, which causes an i_size_read() infinite loop     and denial of service on SMP systems. (CVE-2019-16413)

  - An issue was discovered in write_tpt_entry in     drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel     through 5.3.2. The cxgb4 driver is directly calling     dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of     Service, exploitable if this driver is used on an     architecture for which this stack/DMA interaction has     security relevance. (CVE-2019-17075)

  - The SCTP socket buffer used by a userspace application     is not accounted by the cgroups subsystem. An attacker     can use this flaw to cause a denial of service attack.
    Kernel 3.10.x and 4.18.x branches are believed to be     vulnerable. (CVE-2019-3874)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):Heap-based buffer overflow     in the udf_load_logicalvol function in fs/udf/super.c     in the Linux kernel before 3.4.5 allows remote     attackers to cause a denial of service (system crash)     or possibly have unspecified other impact via a crafted     UDF filesystem.(CVE-2012-3400)The     mmc_ioctl_cdrom_read_data function in     drivers/cdrom/cdrom.c in the Linux kernel through 3.10     allows local users to obtain sensitive information from     kernel memory via a read operation on a malfunctioning     CD-ROM drive.(CVE-2013-2164)The     sctp_sf_do_5_2_4_dupcook function in     net/sctp/sm_statefuns.c in the SCTP implementation in     the Linux kernel before 3.8.5 does not properly handle     associations during the processing of a duplicate     COOKIE ECHO chunk, which allows remote attackers to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unspecified other impact     via crafted SCTP traffic.(CVE-2013-2206)The (1)     get_user and (2) put_user API functions in the Linux     kernel before 3.5.5 on the v6k and v7 ARM platforms do     not validate certain addresses, which allows attackers     to read or modify the contents of arbitrary kernel     memory locations via a crafted application, as     exploited in the wild against Android devices in     October and November 2013.(CVE-2013-6282)An issue was     discovered in the Linux kernel before 4.20. There is a     race condition in smp_task_timedout() and     smp_task_done() in drivers/scsi/libsas/sas_expander.c,     leading to a use-after-free.(CVE-2018-20836)The Siemens     R3964 line discipline driver in drivers/tty/n_r3964.c     in the Linux kernel before 5.0.8 has multiple race     conditions.(CVE-2019-11486)The Linux kernel before     5.1-rc5 allows page->_refcount reference count     overflow, with resultant use-after-free issues, if     about 140 GiB of RAM exists. This is related to     fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h,     kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It     can occur with FUSE requests.(CVE-2019-11487)The     coredump implementation in the Linux kernel before     5.0.10 does not use locking or other mechanisms to     prevent vma layout or vma flags changes while it runs,     which allows local users to obtain sensitive     information, cause a denial of service, or possibly     have unspecified other impact by triggering a race     condition with mmget_not_zero or get_task_mm calls.
    This is related to fs/userfaultfd.c, mm/mmap.c,     fs/proc/task_mmu.c, and     drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)A     n issue was discovered in the Linux kernel before     5.0.7. A NULL pointer dereference can occur when     megasas_create_frame_pool() fails in     megasas_alloc_cmds() in     drivers/scsi/megaraid/megaraid_sas_base.c. This causes     a Denial of Service, related to a     use-after-free.(CVE-2019-11810)An issue was discovered     in the Linux kernel before 5.0.4. There is a     use-after-free upon attempted read access to     /proc/ioports after the ipmi_si module is removed,     related to drivers/char/ipmi/ipmi_si_intf.c,     drivers/char/ipmi/ipmi_si_mem_io.c, and     drivers/char/ipmi/ipmi_si_port_io.c.(CVE-2019-11811)A     flaw was found in the Linux kernel's handle_rx()     function in the [vhost_net] driver. A malicious virtual     guest, under specific conditions, can trigger an     out-of-bounds write in a kmalloc-8 slab on a virtual     host which may lead to a kernel memory corruption and a     system panic. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out. Versions from     v4.16 and newer are vulnerable.(CVE-2018-16880)An issue     was discovered in rds_tcp_kill_sock in net/rds/tcp.c in     the Linux kernel before 5.0.8. There is a race     condition leading to a use-after-free, related to net     namespace cleanup.(CVE-2019-11815)A flaw was found in     the Linux kernel in the function     hid_debug_events_read() in drivers/hid/hid-debug.c file     which may enter an infinite loop with certain     parameters passed from a userspace. A local privileged     user ('root') can cause a system lock up and a denial     of service. Versions from v4.18 and newer are     vulnerable.(CVE-2019-3819)A flaw was found in the Linux     kernel's vfio interface implementation that permits     violation of the user's locked memory limit. If a     device is bound to a vfio driver, such as vfio-pci, and     the local attacker is administratively granted     ownership of the device, it may cause a system memory     exhaustion and thus a denial of service (DoS). Versions     3.10, 4.14 and 4.18 are vulnerable.(CVE-2019-3882)An     infinite loop issue was found in the vhost_net kernel     module in Linux Kernel up to and including v5.1-rc6,     while handling incoming packets in handle_rx(). It     could occur if one end sends packets faster than the     other end can process them. A guest user, maybe remote     one, could use this flaw to stall the vhost_net kernel     thread, resulting in a DoS scenario.(CVE-2019-3900)In     the Linux Kernel before versions 4.20.8 and 4.19.21 a     use-after-free error in the 'sctp_sendmsg()' function     (net/sctp/socket.c) when handling SCTP_SENDALL flag can     be exploited to corrupt memory.(CVE-2019-8956)A flaw     was found in the Linux kernel's implementation of ext4     extent management. The kernel doesn't correctly     initialize memory regions in the extent tree block     which may be exported to a local user to obtain     sensitive information by reading empty/uninitialized     data from the filesystem.(CVE-2019-11833)An issue was     discovered in drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr,     which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is     handled sufficiently and there is no chance for a NULL     pointer dereference.(CVE-2019-12382)An issue was     discovered in the efi subsystem in the Linux kernel     through 5.1.5. phys_efi_set_virtual_address_map in     arch/x86/platform/efi/efi.c and efi_call_phys_prolog in     arch/x86/platform/efi/efi_64.c mishandle memory     allocation failures. NOTE: This id is disputed as not     being an issue because ?All the code touched by the     referenced commit runs only at boot, before any user     processes are started. Therefore, there is no     possibility for an unprivileged user to control     it.(CVE-2019-12380)An issue was discovered in the Linux     kernel before 5.2.3. An out of bounds access exists in     the function hclge_tm_schd_mode_vnet_base_cfg in the     file drivers     et/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.(CVE-2019-     15925)An issue was discovered in     dlpar_parse_cc_property in     arch/powerpc/platforms/pseries/dlpar.c in the Linux     kernel through 5.1.6. There is an unchecked kstrdup of     prop-i1/4zname, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash).(CVE-2019-12614)An issue was discovered in     net/ipv4/sysctl_net_ipv4.c in the Linux kernel before     5.0.11. There is a net/ipv4/tcp_input.c signed integer     overflow in tcp_ack_update_rtt() when userspace writes     a very large integer to     /proc/syset/ipv4/tcp_min_rtt_wlen, leading to a denial     of service or possibly unspecified other impact, aka     CID-19fad20d15a6.(CVE-2019-18805)A flaw was found in     the way PTRACE_TRACEME functionality was handled in the     Linux kernel. The kernel's implementation of ptrace can     inadvertently grant elevated permissions to an attacker     who can then abuse the relationship between the tracer     and the process being traced. This flaw could allow a     local, unprivileged user to increase their privileges     on the system or cause a denial of     service.(CVE-2019-13272)An issue was discovered in     ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux     kernel through 5.1.5. There is an unchecked kmalloc of     new_ra, which might allow an attacker to cause a denial     of service (NULL pointer dereference and system crash).
    NOTE: This has been disputed as not an     issue.(CVE-2019-12378)An issue was discovered in     ip_ra_control in net/ipv4/ip_sockglue.c in the Linux     kernel through 5.1.5. There is an unchecked kmalloc of     new_ra, which might allow an attacker to cause a denial     of service (NULL pointer dereference and system crash).
    NOTE: this is disputed because new_ra is never used if     it is NULL.(CVE-2019-12381)An issue was discovered in     sunxi_divs_clk_setup in drivers/clk/sunxi/clk-sunxi.c     in the Linux kernel through 5.1.5. There is an     unchecked kstrndup of derived_name, which might allow     an attacker to cause a denial of service (NULL pointer     dereference and system crash). NOTE: This id is     disputed as not being an issue because 'The memory     allocation that was not checked is part of a code that     only runs at boot time, before user processes are     started. Therefore, there is no possibility for an     unprivileged user to control it, and no denial of     service.'.(CVE-2019-12455)An issue was discovered in     the MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel     through 5.1.5. It allows local users to cause a denial     of service or possibly have unspecified other impact by     changing the value of ioc_number between two kernel     reads of that value, aka a ''double fetch''     vulnerability. NOTE: a third party reports that this is     unexploitable because the doubly fetched value is not     used.(CVE-2019-12456)An issue was discovered in     get_vdev_port_node_info in arch/sparc/kernel/mdesc.c in     the Linux kernel through 5.1.6. There is an unchecked     kstrdup_const of node_info-i1/4zvdev_port.name, which     might allow an attacker to cause a denial of service     (NULL pointer dereference and system     crash).(CVE-2019-12615)In parse_hid_report_descriptor     in drivers/input/tablet/gtco.c in the Linux kernel     through 5.2.1, a malicious USB device can send an HID     report that triggers an out-of-bounds write during     generation of debugging messages.(CVE-2019-13631)A     vulnerability was found in the Linux kernelaEURtms floppy     disk driver implementation. A local attacker with     access to the floppy device could call set_geometry in     drivers/block/floppy.c, which does not validate the     sect and head fields, causing an integer overflow and     out-of-bounds read. This flaw may crash the system or     allow an attacker to gather information causing     subsequent successful     attacks.(CVE-2019-14283)check_input_term in     sound/usb/mixer.c in the Linux kernel through 5.2.9     mishandles recursion, leading to kernel stack     exhaustion.(CVE-2019-15118)An issue was discovered in     the Linux kernel before 5.2.6. There is a     use-after-free caused by a malicious USB device in the     drivers/media/v4l2-core/v4l2-dev.c driver because     drivers/media/radio/radio-raremono.c does not properly     allocate memory.(CVE-2019-15211)An issue was discovered     in the Linux kernel before 5.0.10. There is a     use-after-free in the sound subsystem because card     disconnection causes certain data structures to be     deleted too early. This is related to sound/core/init.c     and sound/core/info.c.(CVE-2019-15214)An issue was     discovered in the Linux kernel before 5.1.8. There is a     NULL pointer dereference caused by a malicious USB     device in the drivers/media/usb/siano/smsusb.c     driver.(CVE-2019-15218)An issue was discovered in the     Linux kernel before 5.1.8. There is a NULL pointer     dereference caused by a malicious USB device in the     drivers/usb/misc/sisusbvga/sisusb.c     driver.(CVE-2019-15219)An issue was discovered in the     Linux kernel before 5.2.1. There is a use-after-free     caused by a malicious USB device in the     driverset/wireless/intersil/p54/p54usb.c     driver.(CVE-2019-15220)An issue was discovered in the     Linux kernel before 5.1.17. There is a NULL pointer     dereference caused by a malicious USB device in the     sound/usb/line6/pcm.c driver.(CVE-2019-15221)An issue     was discovered in the Linux kernel before 5.0.9. There     is a use-after-free in atalk_proc_exit, related to     net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and     net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)An     issue was discovered in xfs_setattr_nonsize in     fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9.
    XFS partially wedges when a chgrp fails on account of     being out of disk quota. xfs_setattr_nonsize is failing     to unlock the ILOCK after the xfs_qm_vop_chown_reserve     call fails. This is primarily a local DoS attack     vector, but it might result as well in remote DoS if     the XFS filesystem is exported for instance via     NFS.(CVE-2019-15538)An issue was discovered in the     Linux kernel before 5.0.19. There is an out-of-bounds     array access in __xfrm_policy_unlink, which will cause     denial of service, because verify_newpolicy_info in     net/xfrm/xfrm_user.c mishandles directory     validation.(CVE-2019-15666)In the Linux kernel before     5.1.13, there is a memory leak in     drivers/scsi/libsas/sas_expander.c when SAS expander     discovery fails. This will cause a BUG and denial of     service.(CVE-2019-15807)An issue was discovered in the     Linux kernel before 5.0.5. There is a use-after-free     issue when hci_uart_register_dev() fails in     hci_uart_set_proto() in     drivers/bluetooth/hci_ldisc.c.(CVE-2019-15917)An issue     was discovered in the Linux kernel before 5.0.10.
    SMB2_write in fs/cifs/smb2pdu.c has a     use-after-free.(CVE-2019-15919)An issue was discovered     in the Linux kernel before 5.0.10. SMB2_read in     fs/cifs/smb2pdu.c has a use-after-free. NOTE: this was     not fixed correctly in 5.0.10 see the 5.0.11 ChangeLog,     which documents a memory leak.(CVE-2019-15920)An issue     was discovered in the Linux kernel before 5.0.4. The 9p     filesystem did not protect i_size_write() properly,     which causes an i_size_read() infinite loop and denial     of service on SMP systems.(CVE-2019-16413)An issue was     discovered in can_can_gw_rcv in net/can/gw.c in the     Linux kernel through 4.19.13. The CAN frame     modification rules allow bitwise logical operations     that can be also applied to the can_dlc field. Because     of a missing check, the CAN drivers may write arbitrary     content beyond the data registers in the CAN     controller's I/O memory when processing can-gw     manipulated outgoing frames. This is related to     cgw_csum_xor_rel. An unprivileged user can trigger a     system crash (general protection     fault).(CVE-2019-3701)A flaw was found in the Linux     kernel's Marvell wifi chip driver. A heap overflow in     mwifiex_update_bss_desc_with_ie function in     marvell/mwifiex/scan.c allows remote attackers to cause     a denial of service(system crash) or execute arbitrary     code.(CVE-2019-3846)A new software page cache side     channel attack scenario was discovered in operating     systems that implement the very common 'page cache'     caching mechanism. A malicious user/process could use     'in memory' page-cache knowledge to infer access     timings to shared memory and gain knowledge which can     be used to reduce effectiveness of cryptographic     strength by monitoring algorithmic behavior, infer     access patterns of memory to determine code paths     taken, and exfiltrate data to a blinded attacker     through page-granularity access times as a     side-channel.(CVE-2019-5489)In the Android kernel in     the video driver there is a kernel pointer leak due to     a WARN_ON statement. This could lead to local     information disclosure with System execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2019-9455)A vulnerability was found     in the arch/x86/lib/insn-eval.c function in the Linux     kernel. An attacker could corrupt the memory due to a     flaw in use-after-free access to an LDT entry caused by     a race condition between modify_ldt() and a #BR     exception for an MPX bounds violation.(CVE-2019-13233)
