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 :

  - Mounting a crafted EXT4 image read-only leads to an     attacker controlled memory corruption and     SLAB-Out-of-Bounds reads.(CVE-2016-10208i1/4%0

  - An issue was discovered in the hwpoison implementation     in mm/memory-failure.c in the Linux kernel before     5.0.4. When soft_offline_in_use_page() runs on a thp     tail page after pmd is split, an attacker can cause a     denial of service (BUG).(CVE-2019-10124i1/4%0

  - A stack-based buffer overflow flaw was found in the     Linux kernel's early load microcode functionality. On a     system with UEFI Secure Boot enabled, a local,     privileged user could use this flaw to increase their     privileges to the kernel (ring0) level, bypassing     intended restrictions in place.(CVE-2015-2666i1/4%0

  - A flaw was found in the way the Linux kernel's     networking subsystem handled offloaded packets with     multiple layers of encapsulation in the GRO (Generic     Receive Offload) code path. A remote attacker could use     this flaw to trigger unbounded recursion in the kernel     that could lead to stack corruption, resulting in a     system crash.(CVE-2016-8666i1/4%0

  - The ethtool_get_wol function in net/core/ethtool.c in     the Linux kernel through 4.7, as used in Android before     2016-08-05 on Nexus 5 and 7 (2013) devices, does not     initialize a certain data structure, which allows local     users to obtain sensitive information via a crafted     application, aka Android internal bug 28803952 and     Qualcomm internal bug CR570754.(CVE-2014-9900i1/4%0

  - A vulnerability was found in crypto/ahash.c in the     Linux kernel which allows attackers to cause a denial     of service (API operation calling its own callback, and     infinite recursion) by triggering EBUSY on a full     queue.(CVE-2017-7618i1/4%0

  - drivers/misc/qseecom.c in the QSEECOM driver for the     Linux kernel 3.x, as used in Qualcomm Innovation Center     (QuIC) Android contributions for MSM devices and other     products, does not validate certain offset, length, and     base values within an ioctl call, which allows     attackers to gain privileges or cause a denial of     service (memory corruption) via a crafted     application.(CVE-2014-4322i1/4%0

  - An integer overflow vulnerability was found in the     Linux kernel in xt_alloc_table_info, which on 32-bit     systems can lead to small structure allocation and a     copy_from_user based heap corruption.(CVE-2016-3135i1/4%0

  - Stack-based buffer overflow in the     supply_lm_input_write function in     drivers/thermal/supply_lm_core.c in the MSM Thermal     driver for the Linux kernel 3.x, as used in Qualcomm     Innovation Center (QuIC) Android contributions for MSM     devices and other products, allows attackers to cause a     denial of service or possibly have unspecified other     impact via a crafted application that sends a large     amount of data through the debugfs     interface.(CVE-2016-2063i1/4%0

  - The l2tp_ip_recvmsg function in net/l2tp/l2tp_ip.c in     the Linux kernel before 3.12.4 updates a certain length     value before ensuring that an associated data structure     has been initialized, which allows local users to     obtain sensitive information from kernel stack memory     via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system     call.(CVE-2013-7264i1/4%0

  - A bypass was found for the Spectre v1 hardening in the     eBPF engine of the Linux kernel. The code in the     kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic in     various cases, including cases of different branches     with different state or limits to sanitize, leading to     side-channel attacks.(CVE-2019-7308i1/4%0

  - The tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c in the Linux kernel mishandles     inheritance, which allows local users to cause a denial     of service or possibly have unspecified other impact     via crafted system calls, a related issue to     CVE-2017-8890. An unprivileged local user could use     this flaw to induce kernel memory corruption on the     system, leading to a crash. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-9077i1/4%0

  - The cgroup offline implementation in the Linux kernel     through 4.8.11 mishandles certain drain operations,     which allows local users to cause a denial of service     (system hang) by leveraging access to a container     environment for executing a crafted application, as     demonstrated by trinity.(CVE-2016-9191i1/4%0

  - The KVM implementation in the Linux kernel through     4.20.5 has a Use-after-Free.(CVE-2019-7221i1/4%0

  - A NULL pointer dereference flaw was found in the way     the Linux kernel's network subsystem handled socket     creation with an invalid protocol identifier. A local     user could use this flaw to crash the     system.(CVE-2015-8543i1/4%0

  - The drivers/media/usb/dvb-usb-v2/lmedm04.c in the Linux     kernel, through 4.13.11, allows local users to cause a     denial of service (general protection fault and system     crash) or possibly have unspecified other impact via a     crafted USB device, related to a missing warm-start     check and incorrect attach timing     (dm04_lme2510_frontend_attach versus     dm04_lme2510_tuner).(CVE-2017-16538i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's Advanced Linux Sound Architecture (ALSA)     implementation handled user controls. A local,     privileged user could use this flaw to crash the     system.(CVE-2014-4653i1/4%0

  - A vulnerability leading to a local privilege escalation     was found in apparmor in the Linux kernel. When     proc_pid_attr_write() was changed to use memdup_user     apparmor's (interface violating) assumption that the     setprocattr buffer was always a single page was     violated.(CVE-2016-6187i1/4%0

  - A vulnerability was found in the Linux kernel in     'tmpfs' file system. When file permissions are modified     via 'chmod' and the user is not in the owning group or     capable of CAP_FSETID, the setgid bit is cleared in     inode_change_ok(). Setting a POSIX ACL via 'setxattr'     sets the file permissions as well as the new ACL, but     doesn't clear the setgid bit in a similar way this     allows to bypass the check in 'chmod'.(CVE-2017-5551i1/4%0

  - A flaw was found in the Linux Kernel in the     ucma_leave_multicast() function in     drivers/infiniband/core/ucma.c which allows access to a     certain data structure after freeing it in     ucma_process_join(). This allows an attacker to cause a     use-after-free bug and to induce kernel memory     corruption, leading to a system crash or other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2018-14734i1/4%0
