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.

This request can be issued by a user with the CAP_NET_ADMIN capability and may result in     a NULL pointer dereference and system crash. (CVE-2017-12153)

  - The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel through 4.13.3 does not ensure that     the CR8-load exiting and CR8-store exiting L0 vmcs02 controls exist in cases where L1 omits the use     TPR shadow vmcs12 control, which allows KVM L2 guest OS users to obtain read and write access to the     hardware CR8 register. (CVE-2017-12154)

  - The keyctl_read_key function in security/keys/keyctl.c in the Key Management subcomponent in the Linux     kernel before 4.13.5 does not properly consider that a key may be possessed but negatively instantiated,     which allows local users to cause a denial of service (OOPS and system crash) via a crafted KEYCTL_READ     operation.

(CVE-2017-15537)

  - The snd_msnd_interrupt function in sound/isa/msnd/msnd_pinnacle.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-2017-9984)

  - 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.
