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 :

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization(nVMX) feature     enabled(nested=1), is vulnerable to host memory leakage     issue. It could occur while emulating VMXON instruction     in 'handle_vmon'. An L1 guest user could use this flaw     to leak host memory potentially resulting in     DoS.(CVE-2017-2596i1/4%0

  - The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST     extension implementations in the sk_run_filter function     in net/core/filter.c in the Linux kernel through 3.14.3     do not check whether a certain length value is     sufficiently large, which allows local users to cause a     denial of service (integer underflow and system crash)     via crafted BPF instructions. NOTE: the affected code     was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the     vulnerability was announced.(CVE-2014-3144i1/4%0

  - A flaw was found in the Linux kernel when freeing pages     in hugetlbfs. This could trigger a local denial of     service by crashing the kernel.(CVE-2017-15127i1/4%0

  - An issue was discovered in the Linux kernel before 4.8.
    Incorrect access checking in overlayfs mounts could be     used by local attackers to modify or truncate files in     the underlying filesystem.(CVE-2018-16597i1/4%0

  - Memory leak in the cuse_channel_release function in     fs/fuse/cuse.c in the Linux kernel before 4.4 allows     local users to cause a denial of service (memory     consumption) or possibly have unspecified other impact     by opening /dev/cuse many times.(CVE-2015-1339i1/4%0

  - A flaw was found in the way the Linux kernel's nested     NMI handler and espfix64 functionalities interacted     during NMI processing. A local, unprivileged user could     use this flaw to crash the system or, potentially,     escalate their privileges on the     system.(CVE-2015-3290i1/4%0

  - Multiple array index errors in     drivers/hid/hid-multitouch.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_MULTITOUCH is enabled, allow     physically proximate attackers to cause a denial of     service (heap memory corruption, or NULL pointer     dereference and OOPS) via a crafted     device.(CVE-2013-2897i1/4%0

  - A flaw was found in the way the Linux kernel's futex     subsystem handled the requeuing of certain Priority     Inheritance (PI) futexes. A local, unprivileged user     could use this flaw to escalate their privileges on the     system.(CVE-2014-3153i1/4%0

  - The XFS subsystem in the Linux kernel 4.4 and later     allows local users to cause a denial of service     (fdatasync() failure and system hang) by using the vfs     syscall group in the 'trinity' program, as a result of     a page lock order bug in the XFS seek hole/data     implementation.(CVE-2016-8660i1/4%0

  - A flaw was found in the Linux kernel's key management     system where it was possible for an attacker to     escalate privileges or crash the machine. If a user key     gets negatively instantiated, an error code is cached     in the payload area. A negatively instantiated key may     be then be positively instantiated by updating it with     valid data. However, the -i1/4zupdate key type method     must be aware that the error code may be     there.(CVE-2015-8539i1/4%0

  - It was found that the Linux kernel KVM subsystem's     sysenter instruction emulation was not sufficient. An     unprivileged guest user could use this flaw to escalate     their privileges by tricking the hypervisor to emulate     a SYSENTER instruction in 16-bit mode, if the guest OS     did not initialize the SYSENTER model-specific     registers (MSRs). Note: Certified guest operating     systems for Red Hat Enterprise Linux with KVM do     initialize the SYSENTER MSRs and are thus not     vulnerable to this issue when running on a KVM     hypervisor.(CVE-2015-0239i1/4%0

  - An information leak flaw was found in the way the Linux     kernel handled media device enumerate entities IOCTL     requests. A local user able to access the /dev/media0     device file could use this flaw to leak kernel memory     bytes.(CVE-2014-1739i1/4%0

  - The dgnc_mgmt_ioctl function in     drivers/staging/dgnc/dgnc_mgmt.c in the Linux kernel     through 4.3.3 does not initialize a certain structure     member, which allows local users to obtain sensitive     information from kernel memory via a crafted     application.(CVE-2015-7885i1/4%0

  - An information leak was discovered in the Linux kernel     in cdrom_ioctl_drive_status() function in     drivers/cdrom/cdrom.c that could be used by local     attackers to read kernel memory at certain     location.(CVE-2018-16658i1/4%0

  - A flaw was discovered in the Linux kernel's     implementation of VFIO. An attacker issuing an ioctl     can create a situation where memory is corrupted and     modify memory outside of the expected area. This may     overwrite kernel memory and subvert kernel     execution.(CVE-2016-9083i1/4%0

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invvpid     (Invalidate Translations Based on VPID) instructions.
    On hosts with an Intel processor and invppid VM exit     support, an unprivileged guest user could use these     instructions to crash the guest.(CVE-2014-3646i1/4%0

  - An attacker on a network could abuse a flaw in the IPv6     stack fragment reassembly code to induce kernel memory     corruption on the system, possibly leading to a system     crash.(CVE-2016-9755i1/4%0

  - It was found that a regular user could remove xattr     permissions on files by using the chown or write system     calls. A local attacker could use this flaw to deny     elevated permissions from valid users, services, or     applications, potentially resulting in a denial of     service.(CVE-2015-1350i1/4%0

  - arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux     kernel through 4.7 on PowerPC platforms, when     CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS     users to cause a denial of service (host OS infinite     loop) by making a H_CEDE hypercall during the existence     of a suspended transaction.(CVE-2016-5412i1/4%0

  - An issue was discovered in the proc_pid_stack function     in fs/proc/base.c in the Linux kernel. An attacker with     a local account can trick the stack unwinder code to     leak stack contents to userspace. The fix allows only     root to inspect the kernel stack of an arbitrary     task.(CVE-2018-17972i1/4%0
