  - The usbvision driver in the Linux kernel package 3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red     Hat Enterprise Linux (RHEL) 7.1 allows physically proximate attackers to cause a denial of service (panic)     via a nonzero bInterfaceNumber value in a USB device descriptor. (CVE-2015-7833)

  - arch/arm64/kernel/sys.c in the Linux kernel before 4.0 allows local users to bypass the 'strict page     permissions' protection mechanism and modify the system-call table, and consequently gain privileges, by     leveraging write access. (CVE-2015-8967)

  - In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the     userspace API. However, the code allows larger values such as 23. (CVE-2015-9289)

  - The evm_verify_hmac function in security/integrity/evm/evm_main.c in the Linux kernel before 4.5 does not     properly copy data, which makes it easier for local users to forge MAC values via a timing side-channel     attack. (CVE-2016-2085)

  - The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel before 4.5.5 does not     initialize a certain data structure, which allows local users to obtain sensitive information from kernel     stack memory by reading a Netlink message. (CVE-2016-4486)

  - Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel     before 4.6 allows local users to obtain sensitive information from kernel memory by changing a certain     length value, aka a 'double fetch' vulnerability. (CVE-2016-6130)

  - A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, 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 use this flaw to increase their privileges on the host. (CVE-2019-14835)

  - 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: AndroidVersions: Android kernelAndroid ID:
    A-147802478References: Upstream kernel (CVE-2020-0466)

  - 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)

  - There is a flaw reported in the Linux kernel in versions before 5.9 in     drivers/gpu/drm/nouveau/nouveau_sgdma.c in nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The issue     results from the lack of validating the existence of an object prior to performing operations on the     object. An attacker with a local account with a root privilege, can leverage this vulnerability to     escalate privileges and execute code in the context of the kernel. (CVE-2021-20292)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - 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. 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 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 before 5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
    (CVE-2021-30002)

  - ** DISPUTED ** 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)

  - An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-     device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with     special user (CAP_SYS_ADMIN) privilege 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 system     availability. (CVE-2021-31916)

  - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because     the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads     to writing an arbitrary value. (CVE-2021-33033)

  - An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute code in the kernel, aka CID-34b1a1ce1458.
    (CVE-2021-3347)

  - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer     allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an     unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)

  - A flaw was found in the Nosy driver in the Linux kernel. This issue allows a device to be inserted twice     into a doubly-linked list, leading to a use-after-free when one of these devices is removed. The highest     threat from this vulnerability is to confidentiality, integrity, as well as system availability. Versions     before kernel 5.12-rc6 are affected (CVE-2021-3483)

  - kernel/module.c in the Linux kernel before 5.12.14 mishandles Signature Verification, aka     CID-0c18f29aae7c. Without CONFIG_MODULE_SIG, verification that a kernel module is signed, for loading via     init_module, does not occur for a module.sig_enforce=1 command-line argument. (CVE-2021-35039)

    (CVE-2015-8966)

  - 4.0 以前の Linux カーネルの arch/arm64/kernel/sys.c では、ローカルユーザーが厳格なページ権限保護メカニズムをバイパスし、システムコールテーブルを変更することにより、書き込みアクセスを利用して権限を取得する可能性があります。(CVE-2015-8967)

  -4.9までのLinux カーネルのsg実装は、KERNEL_DSオプションが設定されている場合に書き込み操作を適切に制限しないため、ローカルユーザーが任意のカーネルメモリの場所を読み書きしたり、block/bsg.cとdrivers/scsi/sg.cに関連する/dev/sgデバイスへのアクセスを利用してサービス拒否（メモリ解放後使用（Use After Free））を引き起こす可能性があります。注意:  この脆弱性は、CVE-2016-9576の修正が不完全なために存在します。(CVE-2016-10088)

  - 4.11.5より前の Linux カーネル内の sound/core/timer.c が ALSA/dev/snd/timer ドライバーのデータ競合に対して脆弱なため、ローカルユーザーが、他のユーザーに属している情報を読み取れる可能性があります。つまり、read と ioctl が同時に発生したときに、初期化されていないメモリコンテンツが開示される可能性があります。
    (CVE-2017-1000380)

  -4.10.7までのLinuxカーネルのdrivers/gpu/drm/vmwgfx/vmwgfx_surface.cのvmw_gb_surface_define_ioctl関数が、特定のレベルデータを検証していないため、ローカルユーザーが、/dev/dri/renderD*デバイス用の細工されたioctl呼び出しを介して、サービス拒否（システムハングアップ）を引き起こす可能性があります。（CVE-2017-7346）

  - 4.10.13 までの Linux カーネルの NFSv2 と NFSv3 のサーバーの実装には、バッファの終端に対する特定のチェックがありません。そのため、リモート攻撃者が、細工されたリクエストを介して、ポインター演算エラーをトリガーしたり、その他の詳細不明な影響を与えたりする可能性があります。これは s/nfsd/nfs3xdr.c および fs/nfsd/nfsxdr.c に関連しています。

  - arch/arm64/kernel/sys.c in the Linux kernel before 4.0 allows local users to bypass the strict page     permissions protection mechanism and modify the system-call table, and consequently gain privileges, by     leveraging write access. (CVE-2015-8967)

  - The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in     situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary     kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg     device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an     incomplete fix for CVE-2016-9576. (CVE-2016-10088)

  - sound/core/timer.c in the Linux kernel before 4.11.5 is vulnerable to a data race in the ALSA     /dev/snd/timer driver resulting in local users being able to read information belonging to other users,     i.e., uninitialized memory contents may be disclosed when a read and an ioctl happen at the same time.
    (CVE-2017-1000380)

  - The vmw_gb_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel     through 4.10.7 does not validate certain levels data, which allows local users to cause a denial of     service (system hang) via a crafted ioctl call for a /dev/dri/renderD* device. (CVE-2017-7346)

  - The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the     end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have     unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.
    (CVE-2017-7895)

  - The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows     local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer     underflow. (CVE-2017-8924)

  - The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel before 4.10.4 allows local     users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling.
    (CVE-2017-8925)

  - The vmw_gb_surface_define_ioctl function (accessible via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.11.4 defines a backup_handle     variable but does not give it an initial value. If one attempts to create a GB surface, with a previously     allocated DMA buffer to be used as a backup buffer, the backup_handle variable does not get written to and     is then later returned to user space, allowing local users to obtain sensitive information from     uninitialized kernel memory via a crafted ioctl call. (CVE-2017-9605)

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

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 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):The uas driver in the     Linux kernel before 4.13.6 allows local users to cause     a denial of service (out-of-bounds read and system     crash), or possibly have unspecified other impacts via     a crafted USB device, related to     drivers/usb/storage/uas-detect.h and     drivers/usb/storage/uas.c.(CVE-2017-16530)The     implementation of big key management in     security/keys/big_key.c in the Linux kernel before     4.8.7 mishandles unsuccessful crypto registration in     conjunction with successful key-type registration,     which allows local users to cause a denial of service     (NULL pointer dereference and panic) or possibly have     unspecified other impact via a crafted application that     uses the big_key data type.(CVE-2016-9313)The Linux     kernel allows remote attackers to execute arbitrary     code via UDP traffic that triggers an unsafe second     checksum calculation during execution of a recv system     call with the MSG_PEEK flag. This may create a kernel     panic or memory corruption leading to privilege     escalation.(CVE-2016-10229)Buffer overflow in the     exitcode_proc_write function in     arch/um/kernel/exitcode.c in the Linux kernel before     3.12 allows local users to cause a denial of service or     possibly have unspecified other impact by leveraging     root privileges for a write operation.(CVE-2013-4512)It     was found that unsharing a mount namespace could allow     a user to see data beneath their restricted     namespace.(CVE-2014-9717)A divide-by-zero flaw was     discovered in the Linux kernel built with KVM     virtualization support(CONFIG_KVM). The flaw occurs in     the KVM module's Programmable Interval Timer(PIT)     emulation, when PIT counters for channel 1 or 2 are set     to zero(0) and a privileged user inside the guest     attempts to read these counters. A privileged guest     user with access to PIT I/O ports could exploit this     issue to crash the host kernel (denial of     service).(CVE-2015-7513)The ims_pcu_parse_cdc_data     function in drivers/input/misc/ims-pcu.c in the Linux     kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (system crash)     via a USB device without both a master and a slave     interface.(CVE-2016-3689)Stack-based buffer overflow in     the brcmf_cfg80211_start_ap() function in     'driverset/wireless/broadcom/brcm80211/brcmfmac/cfg8021     1.c' in the Linux kernel before 4.7.5 allows local     users to cause a denial of service (system crash) or     possibly have unspecified other impact via a long SSID     Information Element in a command to a Netlink     socket.(CVE-2016-8658)drivers/hid/hid-sony.c in the     Human Interface Device (HID) subsystem in the Linux     kernel through 3.11, when CONFIG_HID_SONY is enabled,     allows physically proximate attackers to cause a denial     of service (heap-based out-of-bounds write) via a     crafted device.(CVE-2013-2890)An issue where a provided     address with access_ok() is not checked was discovered     in i915_gem_execbuffer2_ioctl in     drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux     kernel through 4.19.13. A local attacker can craft a     malicious IOCTL function call to overwrite arbitrary     kernel memory, resulting in a Denial of Service or     privilege escalation.(CVE-2018-20669)It was found that     the permission checks performed by the Linux kernel     when a netlink message was received were not     sufficient. A local, unprivileged user could     potentially bypass these restrictions by passing a     netlink socket as stdout or stderr to a more privileged     process and altering the output of this     process.(CVE-2014-0181)An issue was discovered in the     XFS filesystem in fs/xfs/libxfs/xfs_attr_leaf.c in the     Linux kernel. A NULL pointer dereference may occur for     a corrupted xfs image after xfs_da_shrink_inode() is     called with a NULL bp. This can lead to a system crash     and a denial of service.(CVE-2018-13094)The     irda_setsockopt function in net/irda/af_irda.c in the     Linux kernel, through 4.16, allows local users to cause     a denial of service (due to a use-after-free of the     ias_object and a system crash) or possibly have     unspecified other impact by leveraging an AF_IRDA     socket.(CVE-2018-6555)The x86/fpu (Floating Point Unit)     subsystem in the Linux kernel, when a processor     supports the xsave feature but not the xsaves feature,     does not correctly handle attempts to set reserved bits     in the xstate header via the ptrace() or rt_sigreturn()     system call. This allows local users to read the FPU     registers of other processes on the system, related to     arch/x86/kernel/fpu/regset.c and     arch/x86/kernel/fpu/signal.c.(CVE-2017-15537)The     fst_get_iface function in driverset/wan/farsync.c in     the Linux kernel before 3.11.7 does not properly     initialize a certain data structure, which allows local     users to obtain sensitive information from kernel     memory by leveraging the CAP_NET_ADMIN capability for     an SIOCWANDEV ioctl call.(CVE-2014-1444)In the Linux     kernel, through 4.15.4, the floppy driver reveals the     addresses of kernel functions and global variables     using printk calls within the function show_floppy in     drivers/block/floppy.c. An attacker can read this     information from dmesg and use the addresses to find     the locations of kernel code and data and bypass kernel     security protections such as KASLR.(CVE-2018-7273)A     flaw in 'arch/arm64/kernel/sys.c' in the Linux kernel     allows local users to bypass the 'strict page     permissions' protection mechanism and modify the     system-call table and, consequently, gain privileges by     leveraging write access.(CVE-2015-8967)The Linux kernel     before 3.11 on ARM platforms, as used in Android before     2016-08-05 on Nexus 5 and 7 (2013) devices, does not     properly consider user-space access to the TPIDRURW     register, which allows local users to gain privileges     via a crafted application, aka Android internal bug     28749743 and Qualcomm internal bug     CR561044.(CVE-2014-9870)A NULL pointer dereference     security flaw was found in the Linux kernel in the     vcpu_scan_ioapic() function in arch/x86/kvm/x86.c. This     allows local users with certain privileges to cause a     denial of service via a crafted system call to the KVM     subsystem.(CVE-2018-19407)It was found that current     implementation of kl5kusb105 driver failed to detect     short transfers when attempting to read the line state     and logged the content of the uninitialized heap     transfer buffer.(CVE-2017-5549)
