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 :

  - Array index error in the tcm_vhost_make_tpg function in     drivers/vhost/scsi.c in the Linux kernel before 4.0     might allow guest OS users to cause a denial of service     (memory corruption) or possibly have unspecified other     impact via a crafted VHOST_SCSI_SET_ENDPOINT ioctl     call. NOTE: the affected function was renamed to     vhost_scsi_make_tpg before the vulnerability was     announced.(CVE-2015-4036i1/4%0

  - The llc_cmsg_rcv function in net/llc/af_llc.c in the     Linux kernel before 4.5.5 does not initialize a certain     data structure, which allows attackers to obtain     sensitive information from kernel stack memory by     reading a message.(CVE-2016-4485i1/4%0

  - The nr_recvmsg function in net/netrom/af_netrom.c in     the Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7269i1/4%0

  - The mct_u232_msr_to_state function in     drivers/usb/serial/mct_u232.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted USB device without two     interrupt-in endpoint descriptors.(CVE-2016-3136i1/4%0

  - An out-of-bounds memory access flaw, CVE-2014-7825, was     found in the syscall tracing functionality of the Linux     kernel's perf subsystem. A local, unprivileged user     could use this flaw to crash the system. Additionally,     an out-of-bounds memory access flaw, CVE-2014-7826, was     found in the syscall tracing functionality of the Linux     kernel's ftrace subsystem. On a system with ftrace     syscall tracing enabled, a local, unprivileged user     could use this flaw to crash the system, or escalate     their privileges.(CVE-2014-7826i1/4%0

  - Linux kernel built with the Kernel-based Virtual     Machine (CONFIG_KVM) support is vulnerable to a null     pointer dereference flaw. It could occur on x86     platform, when emulating an undefined instruction. An     attacker could use this flaw to crash the host kernel     resulting in DoS.(CVE-2016-8630i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound access in     ext4_get_group_info function, a denial of service, and     a system crash by mounting and operating on a crafted     ext4 filesystem image.(CVE-2018-10881i1/4%0

  - The arch_timer_reg_read_stable macro in     arch/arm64/include/asm/arch_timer.h in the Linux kernel     before 4.13 allows local users to cause a denial of     service (infinite recursion) by writing to a file under     /sys/kernel/debug in certain circumstances, as     demonstrated by a scenario involving debugfs, ftrace,     PREEMPT_TRACER, and     FUNCTION_GRAPH_TRACER.(CVE-2017-18261i1/4%0

  - The ip6_route_add function in net/ipv6/route.c in the     Linux kernel through 3.13.6 does not properly count the     addition of routes, which allows remote attackers to     cause a denial of service (memory consumption) via a     flood of ICMPv6 Router Advertisement     packets.(CVE-2014-2309i1/4%0

  - In the Linux kernel before 4.20.2, kernel/sched/fair.c     mishandles leaf cfs_rq's, which allows attackers to     cause a denial of service (infinite loop in     update_blocked_averages) or possibly have unspecified     other impact by inducing a high load.(CVE-2018-20784i1/4%0

  - An issue was discovered in the F2FS filesystem code in     fs/f2fs/inline.c in the Linux kernel. A denial of     service due to the out-of-bounds memory access can     occur for a modified f2fs filesystem     image.(CVE-2018-13099i1/4%0

  - An out-of-bounds write vulnerability was found in the     Linux kernel's vmw_surface_define_ioctl() function, in     the 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file. Due     to the nature of the flaw, privilege escalation cannot     be fully ruled out, although we believe it is     unlikely.(CVE-2017-7294i1/4%0

  - A flaw was found in the way the Linux kernel's KVM     subsystem handled non-canonical addresses when     emulating instructions that change the RIP (for     example, branches or calls). A guest user with access     to an I/O or MMIO region could use this flaw to crash     the guest.(CVE-2014-3647i1/4%0

  - The __munlock_pagevec function in mm/mlock.c in the     Linux kernel, before 4.11.4, allows local users to     cause a denial of service (NR_MLOCK accounting     corruption) via crafted use of mlockall and munlockall     system calls.(CVE-2017-18221i1/4%0

  - ** RESERVED ** This candidate has been reserved by an     organization or individual that will use it when     announcing a new security problem. When the candidate     has been publicized, the details for this candidate     will be provided.(CVE-2018-1120i1/4%0

  - The proc_connectinfo() function in     'drivers/usb/core/devio.c' in the Linux kernel through     4.6 does not initialize a certain data structure, which     allows local users to obtain sensitive information from     kernel stack memory via a crafted USBDEVFS_CONNECTINFO     ioctl call. The stack object 'ci' has a total size of 8     bytes. Its last 3 bytes are padding bytes which are not     initialized and are leaked to     userland.(CVE-2016-4482i1/4%0

  - A vulnerability was found in the Linux kernel. An     unprivileged local user could trigger oops in     shash_async_export() by attempting to force the     in-kernel hashing algorithms into decrypting an empty     data set.(CVE-2016-8646i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. An invalid NULL pointer dereference     in btrfs_root_node() when mounting a crafted btrfs     image is due to a lack of chunk block group mapping     validation in btrfs_read_block_groups() in the     fs/btrfs/extent-tree.c function and a lack of     empty-tree checks in check_leaf() in     fs/btrfs/tree-checker.c function. This could lead to a     system crash and a denial of service.(CVE-2018-14612i1/4%0

  - It was found that the Linux kernel's TCP/IP protocol     suite implementation for IPv6 allowed the Hop Limit     value to be set to a smaller value than the default     one. An attacker on a local network could use this flaw     to prevent systems on that network from sending or     receiving network packets.(CVE-2015-2922i1/4%0

  - A NULL-pointer dereference flaw was found in the     kernel, which is caused by a race between revoking a     user-type key and reading from it. The issue could be     triggered by an unprivileged user with a local account,     causing the kernel to crash (denial of     service).(CVE-2015-7550i1/4%0
