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):A flaw was found in Linux     kernel in the ext4 filesystem code. A use-after-free is     possible in ext4_ext_remove_space() function when     mounting and operating a crafted ext4     image.(CVE-2018-10876)A flaw was found in the Linux     kernel. A use-after-free was found in the way the     console subsystem was using ioctls KDGKBSENT and     KDSKBSENT. A local user could use this flaw to get read     memory access out of bounds. The highest threat from     this vulnerability is to data     confidentiality.(CVE-2020-25656)A flaw was found in the     way RTAS handled memory accesses in userspace to kernel     communication. On a locked down (usually due to Secure     Boot) guest system running on top of PowerVM or KVM     hypervisors (pseries platform) a root like local user     could use this flaw to further increase their     privileges to that of a running     kernel.(CVE-2020-27777)A information disclosure     vulnerability in the Upstream kernel encrypted-keys.
    Product: Android. Versions: Android kernel. Android ID:
    A-70526974.(CVE-2017-13305)A race condition was found     in the Linux kernels implementation of the floppy disk     drive controller driver software. The impact of this     issue is lessened by the fact that the default     permissions on the floppy device (/dev/fd0) are     restricted to root. If the permissions on the device     have changed the impact changes greatly. In the default     configuration root (or equivalent) permissions are     required to attack this flaw.(CVE-2021-20261)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->name, 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     fs/xfs/xfs_icache.c in the Linux kernel through 4.17.3.
    There is a NULL pointer dereference and panic in     lookup_slow() on a NULL inode->i_ops pointer when doing     pathwalks on a corrupted xfs image. This occurs because     of a lack of proper validation that cached inodes are     free during allocation.(CVE-2018-13093)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)An issue was discovered in the     Linux kernel through 5.11.3. A kernel pointer leak can     be used to determine the address of the iscsi_transport     structure. When an iSCSI transport is registered with     the iSCSI subsystem, the transport's handle is     available to unprivileged users via the sysfs file     system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)An issue was     discovered in the Linux kernel through 5.11.3. Certain     iSCSI data structures do not have appropriate length     constraints or checks, and can exceed the PAGE_SIZE     value. An unprivileged user can send a Netlink message     that is associated with iSCSI, and has a length up to     the maximum length of a Netlink     message.(CVE-2021-27365)An issue was discovered in the     Linux kernel through 5.11.3.
    drivers/scsi/scsi_transport_iscsi.c is adversely     affected by the ability of an unprivileged user to     craft Netlink messages.(CVE-2021-27364)An issue was     discovered in yurex_read in drivers/usb/misc/yurex.c in     the Linux kernel before 4.17.7. Local attackers could     use user access read/writes with incorrect bounds     checking in the yurex USB driver to crash the kernel or     potentially escalate     privileges.(CVE-2018-16276)drivers/infiniband/core/ucma     .c in the Linux kernel through 4.17.11 allows     ucma_leave_multicast to access a certain data structure     after a cleanup step in ucma_process_join, which allows     attackers to cause a denial of service     (use-after-free).(CVE-2018-14734)In create_pinctrl of     core.c, there is a possible out of bounds read due to a     use after free. This could lead to local information     disclosure with no additional execution privileges     needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-140550171(CVE-2020-0427)In     do_epoll_ctl and ep_loop_check_proc of eventpoll.c,     there is a possible use after free due to a logic     error. This could lead to local escalation of privilege     with no additional execution privileges needed. User     interaction is not needed for exploitation.Product:

    A-147802478References: Upstream kernel(CVE-2020-0466)In     fs/ocfs2/cluster/ nodemanager.c in the Linux kernel     before 4.15, local users can cause a denial of service     (NULL pointer dereference and BUG) because a required     mutex is not used.(CVE-2017-18216)In the Linux kernel     before 5.2, a setxattr operation, after a mount of a     crafted ext4 image, can cause a slab-out-of-bounds     write access because of an ext4_xattr_set_entry     use-after-free in fs/ext4/xattr.c when a large old_size     value is used in a memset call, aka     CID-345c0dbf3a30.(CVE-2019-19319)In the Linux kernel     before version 4.12, Kerberos 5 tickets decoded when     using the RXRPC keys incorrectly assumes the size of a     field. This could lead to the size-remaining variable     wrapping and the data pointer going over the end of the     buffer. This could possibly lead to memory corruption     and possible privilege escalation.(CVE-2017-7482)In     uvc_scan_chain_forward of uvc_driver.c, there is a     possible linked list corruption due to an unusual root     cause. This could lead to local escalation of privilege     in the kernel with no additional execution privileges     needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-111893654References: Upstream     kernel(CVE-2020-0404)In various methods of     hid-multitouch.c, there is a possible out of bounds     write due to a missing bounds check. This could lead to     local escalation of privilege with no additional     execution privileges needed. User interaction is not     needed for exploitation.Product: AndroidVersions:
    Android kernelAndroid ID: A-162844689References:
    Upstream kernel(CVE-2020-0465)It was found that the raw     midi kernel driver does not protect against concurrent     access which leads to a double realloc (double free) in     snd_rawmidi_input_params() and     snd_rawmidi_output_status() which are part of     snd_rawmidi_ioctl() handler in rawmidi.c file. A     malicious local attacker could possibly use this for     privilege escalation.(CVE-2018-10902)Linux kernel ext4     filesystem is vulnerable to an out-of-bound access in     the ext4_ext_drop_refs() function when operating on a     crafted ext4 filesystem image.(CVE-2018-10877)Linux     kernel is vulnerable to a stack-out-of-bounds write in     the ext4 filesystem code when mounting and writing to a     crafted ext4 image in ext4_update_inline_data(). An     attacker could use this to cause a system crash and a     denial of service.(CVE-2018-10880)Linux Kernel contains     an out-of-bounds read flaw in the asn1_ber_decoder()     function in lib/asn1_decoder.c that is triggered when     decoding ASN.1 data. This may allow a remote attacker     to disclose potentially sensitive memory     contents.(CVE-2018-9383)use-after-free read in     sunkbd_reinit in     drivers/input/keyboard/sunkbd.c(CVE-2020-25669)mwifiex_     cmd_802_11_ad_hoc_start in drivers/     net/wireless/marvell/mwifiex/join.c in the Linux kernel     through 5.10.4 might allow remote attackers to execute     arbitrary code via a long SSID value, aka     CID-5c455c5ab332.(CVE-2020-36158)fs/ nfsd/ nfs3xdr.c in     the Linux kernel through 5.10.8, when there is an NFS     export of a subdirectory of a filesystem, allows remote     attackers to traverse to other parts of the filesystem     via READDIRPLUS. NOTE: some parties argue that such a     subdirectory export is not intended to prevent this     attack see also the exports(5) no_subtree_check default     behavior.(CVE-2021-3178)In the Linux kernel before     4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c     mishandles reference counting because of a race     condition, leading to a     use-after-free.(CVE-2019-6974)The KVM implementation in     the Linux kernel through 4.20.5 has a     Use-after-Free.(CVE-2019-7221)A flaw was found in the     JFS filesystem code. This flaw allows a local attacker     with the ability to set extended attributes to panic     the system, causing memory corruption or escalating     privileges. The highest threat from this vulnerability     is to confidentiality, integrity, as well as system     availability.(CVE-2020-27815)An out-of-bounds (OOB)     memory access flaw was found in x25_bind in     net/x25/af_x25.c in the Linux kernel. A bounds check     failure allows a local attacker with a user account on     the system to gain access to out-of-bounds memory,     leading to a system crash or a leak of internal kernel     information. The highest threat from this vulnerability     is to confidentiality, integrity, as well as system     availability.(CVE-2020-35519)In     drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux     kernel through 5.11.8, the RPA PCI Hotplug driver has a     user-tolerable buffer overflow when writing a new     device name to the driver from userspace, allowing     userspace to write data to the kernel stack frame     directly. This occurs because add_slot_store and     remove_slot_store mishandle drc_name '\0' termination,     aka CID-cc7a0bb058b8.(CVE-2021-28972)A NULL pointer     dereference was found in the net/rds/rdma.c
    __rds_rdma_map() function in the Linux kernel before     4.14.7 allowing local attackers to cause a system panic     and a denial-of-service, related to RDS_GET_MR and     RDS_GET_MR_FOR_DEST.(CVE-2018-7492)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 kernel in Android before     2016-08-05 on Nexus 7 (2013) devices allows attackers     to gain privileges via a crafted application, aka     internal bug 28522518.(CVE-2016-3857)The KVM     implementation in the Linux kernel through 4.14.7     allows attackers to obtain potentially sensitive     information from kernel memory, aka a write_mmio     stack-based out-of-bounds read, related to     arch/x86/kvm/x86.c and     include/trace/events/kvm.h.(CVE-2017-17741)The     sctp_process_param function in net/sctp/sm_make_chunk.c     in the SCTP implementation in the Linux kernel before     3.17.4, when ASCONF is used, allows remote attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a malformed INIT     chunk.(CVE-2014-7841)The XFS subsystem in the Linux     kernel through 4.8.2 allows local users to cause a     denial of service (fdatasync failure and system hang)     by using the vfs syscall group in the trinity program,     related to a 'page lock order bug in the XFS seek     hole/data implementation.'(CVE-2016-8660)The     xfs_dinode_verify function in     fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel     through 4.16.3 allows local users to cause a denial of     service (xfs_ilock_attr_map_shared invalid pointer     dereference) via a crafted xfs image.(CVE-2018-10322)
