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 snd_msndmidi_input_read function in     sound/isa/msnd/msnd_midi.c in the Linux kernel through     4.11.7 allows local users to cause a denial of service     (over-boundary access) or possibly have unspecified     other impact by changing the value of a message queue     head pointer between two kernel reads of that value,     aka a 'double fetch' vulnerability.(CVE-2017-9985i1/4%0

  - An assertion failure issue was found in the Linux     kernel's KVM hypervisor module built to support     visualization on ARM64 architecture platforms. The     failure could occur while accessing Performance     Monitors Cycle Count Register (PMCCNTR) from a guest. A     privileged guest user could use this flaw to crash the     host kernel resulting in denial of     service.(CVE-2017-12168i1/4%0

  - The iscsi_if_rx() function in     'drivers/scsi/scsi_transport_iscsi.c' in the Linux     kernel from v2.6.24-rc1 through 4.13.2 allows local     users to cause a denial of service (a system panic) by     making a number of certain syscalls by leveraging     incorrect length validation in the kernel     code.(CVE-2017-14489i1/4%0

  - The hdpvr_probe function in     drivers/media/usb/hdpvr/hdpvr-core.c in the Linux     kernel through 4.13.11 allows local users to cause a     denial of service (improper error handling and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16644i1/4%0

  - The dvb frontend management subsystem in the Linux     kernel contains a use-after-free which can allow a     malicious user to write to memory that may be assigned     to another kernel structure. This could create memory     corruption, panic, or possibly other side     affects.(CVE-2017-16648i1/4%0

  - It was found that the Linux kernel's IPv6     implementation mishandled socket options. A local     attacker could abuse concurrent access to the socket     options to escalate their privileges, or cause a denial     of service (use-after-free and system crash) via a     crafted sendmsg system call.(CVE-2016-3841i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause a use-after-free in     ext4_xattr_set_entry function and a denial of service     or unspecified other impact may occur by renaming a     file in a crafted ext4 filesystem     image.(CVE-2018-10879i1/4%0

  - A race condition was found in the Linux kernel, present     since v3.14-rc1 through v4.12. The race happens between     threads of inotify_handle_event() and vfs_rename()     while running the rename operation against the same     file. As a result of the race the next slab data or the     slab's free list pointer can be corrupted with     attacker-controlled data, which may lead to the     privilege escalation.(CVE-2017-7533i1/4%0

  - A privilege-escalation vulnerability was discovered in     the Linux kernel built with User Namespace     (CONFIG_USER_NS) support. The flaw occurred when the     ptrace() system call was used on a root-owned process     to enter a user namespace. A privileged namespace user     could exploit this flaw to potentially escalate their     privileges on the system, outside the original     namespace.(CVE-2015-8709i1/4%0

  - Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     before 4.5.2 allows local users to cause a denial of     service (memory corruption and system crash, or     spinlock) or possibly have unspecified other impact by     removing a network namespace, related to the     ppp_register_net_channel and ppp_unregister_channel     functions.(CVE-2016-4805i1/4%0

  - A flaw was found in the way the Linux kernel's     kvm_iommu_map_pages() function handled IOMMU mapping     failures. A privileged user in a guest with an assigned     host device could use this flaw to crash the     host.(CVE-2014-3601i1/4%0

  - A flaw was found in the Linux kernel's implementation     of associative arrays introduced in 3.13. This     functionality was backported to the 3.10 kernels in Red     Hat Enterprise Linux 7. The flaw involved a null     pointer dereference in assoc_array_apply_edit() due to     incorrect node-splitting in assoc_array implementation.
    This affects the keyring key type and thus key addition     and link creation operations may cause the kernel to     panic.(CVE-2017-12193i1/4%0

  - Multiple race conditions in drivers/char/adsprpc.c and     drivers/char/adsprpc_compat.c in the ADSPRPC driver for     the Linux kernel 3.x, as used in Qualcomm Innovation     Center (QuIC) Android contributions for MSM devices and     other products, allow attackers to cause a denial of     service (zero-value write) or possibly have unspecified     other impact via a COMPAT_FASTRPC_IOCTL_INVOKE_FD ioctl     call.(CVE-2015-0572i1/4%0

  - The sanity_check_ckpt function in fs/f2fs/super.c in     the Linux kernel before version 4.12.4 does not     validate the blkoff and segno arrays. This allows an     unprivileged, local user to cause a system panic and     DoS. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.(CVE-2017-10663i1/4%0

  - A stack overflow flaw caused by infinite recursion was     found in the way the Linux kernel's Universal Disk     Format (UDF) file system implementation processed     indirect Information Control Blocks (ICBs). An attacker     with physical access to the system could use a     specially crafted UDF image to crash the     system.(CVE-2014-6410i1/4%0

  - Race condition in the ion_ioctl function in     drivers/staging/android/ion/ion.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) by calling     ION_IOC_FREE on two CPUs at the same     time.(CVE-2016-9120i1/4%0

  - drivers/hid/hid-picolcd_core.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_PICOLCD is enabled, allows     physically proximate attackers to cause a denial of     service (NULL pointer dereference and OOPS) via a     crafted device.(CVE-2013-2899i1/4%0

  - A flaw was found in the Linux kernel's implementation     of overlayfs. An attacker can leak file resources in     the system by opening a large file with write     permissions on a overlay filesystem that is     insufficient to deal with the size of the write.When     unmounting the underlying device, the system is unable     to free an inode and this will consume resources.
    Repeating this for all available inodes and memory will     create a denial of service situation.(CVE-2015-8953i1/4%0

  - Buffer overflow in the mp_override_legacy_irq()     function in arch/x86/kernel/acpi/boot.c in the Linux     kernel through 4.12.2 allows local users to gain     privileges via a crafted ACPI table.(CVE-2017-11473i1/4%0

  - Use-after-free vulnerability in the     kvm_ioctl_create_device function in virt/kvm/kvm_main.c     in the Linux kernel before 4.8.13 allows host OS users     to cause a denial of service (host OS crash) or     possibly gain privileges via crafted ioctl calls on the     /dev/kvm device.(CVE-2016-10150i1/4%0
