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 walk_hugetlb_range()     function in 'mm/pagewalk.c' file in the Linux kernel     from v4.0-rc1 through v4.15-rc1 mishandles holes in     hugetlb ranges. This allows local users to obtain     sensitive information from uninitialized kernel memory     via crafted use of the mincore() system     call.(CVE-2017-16994)In the Linux kernel before 4.7,     the amd_gpio_remove function in     drivers/pinctrl/pinctrl-amd.c calls the     pinctrl_unregister function, leading to a double     free.(CVE-2017-18174)In the Linux kernel through     4.20.11, af_alg_release() in crypto/af_alg.c neglects     to set a NULL value for a certain structure member,     which leads to a use-after-free in     sockfs_setattr.(CVE-2019-8912)A security flaw was found     in the Linux kernel that an attempt to move page mapped     by AIO ring buffer to the other node triggers NULL     pointer dereference at trace_writeback_dirty_page(),     because aio_fs_backing_dev_info.dev is     0.(CVE-2016-3070)The NFSv4 implementation in the Linux     kernel through 4.11.1 allows local users to cause a     denial of service (resource consumption) by leveraging     improper channel callback shutdown when unmounting an     NFSv4 filesystem, aka a 'module reference and kernel     daemon' leak.(CVE-2017-9059)When creating audit records     for parameters to executed children processes, an     attacker can convince the Linux kernel audit subsystem     can create corrupt records which may allow an attacker     to misrepresent or evade logging of executing     commands.(CVE-2016-6136)A use-after-free vulnerability     was found in a network namespaces code affecting the     Linux kernel since v4.0-rc1 through v4.15-rc5. The     function get_net_ns_by_id() does not check for the     net::count value after it has found a peer network in     netns_ids idr which could lead to double free and     memory corruption. This vulnerability could allow an     unprivileged local user 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 it is thought to be     unlikely.(CVE-2017-15129)A NULL pointer dereference     flaw was found in the rds_ib_laddr_check() function in     the Linux kernel's implementation of Reliable Datagram     Sockets (RDS). A local, unprivileged user could use     this flaw to crash the system.(CVE-2013-7339)A flaw was     found in the Linux kernel key management subsystem in     which a local attacker could crash the kernel or     corrupt the stack and additional memory (denial of     service) by supplying a specially crafted RSA key. This     flaw panics the machine during the verification of the     RSA key.(CVE-2016-8650)The uio_mmap_physical function     in drivers/uio/uio.c in the Linux kernel before 3.12     does not validate the size of a memory block, which     allows local users to cause a denial of service (memory     corruption) or possibly gain privileges via crafted     mmap operations, a different vulnerability than     CVE-2013-4511.(CVE-2013-6763)In the Linux kernel before     4.20.5, attackers can trigger a     drivers/char/ipmi/ipmi_msghandler.c use-after-free and     OOPS by arranging for certain simultaneous execution of     the code, as demonstrated by a 'service ipmievd     restart' loop.(CVE-2019-9003)An integer overflow flaw     was found in the way the Linux kernel randomized the     stack for processes on certain 64-bit architecture     systems, such as x86-64, causing the stack entropy to     be reduced by four.(CVE-2015-1593)The     compat_sys_recvmmsg function in net/compat.c in the     Linux kernel before 3.13.2, when CONFIG_X86_X32 is     enabled, allows local users to gain privileges via a     recvmmsg system call with a crafted timeout pointer     parameter.(CVE-2014-0038)The kill_something_info     function in kernel/signal.c in the Linux kernel before     4.13, when an unspecified architecture and compiler is     used, might allow local users to cause a denial of     service via an INT_MIN     argument.(CVE-2018-10124)arch/s390/kernel/head64.S in     the Linux kernel before 3.13.5 on the s390 platform     does not properly handle attempted use of the linkage     stack, which allows local users to cause a denial of     service (system crash) by executing a crafted     instruction.(CVE-2014-2039)A flaw was found in the     Linux kernel in that the aoedisk_debugfs_show()     function in drivers/block/aoe/aoeblk.c allows local     users to obtain some kernel address information by     reading a debugfs file. This address is not useful to     commit a further attack.(CVE-2018-7754)ALSA sequencer     core initializes the event pool on demand by invoking     snd_seq_pool_init() when the first write happens and     the pool is empty. A user can reset the pool size     manually via ioctl concurrently, and this may lead to     UAF or out-of-bound access.(CVE-2018-7566)In the     function wmi_set_ie(), the length validation code does     not handle unsigned integer overflow properly. As a     result, a large value of the 'ie_len' argument can     cause a buffer overflow in all Android releases from     CAF (Android for MSM, Firefox OS for MSM, QRD Android)     using the Linux Kernel.(CVE-2018-5848)The Linux kernel     does not properly initialize memory in messages passed     between virtual guests and the host operating system in     the vhost/vhost.c:vhost_new_msg() function. This can     allow local privileged users to read some kernel memory     contents when reading from the /dev/vhost-net device     file.(CVE-2018-1118)Systems with microprocessors     utilizing speculative execution and speculative     execution of memory reads before the addresses of all     prior memory writes are known may allow unauthorized     disclosure of information to an attacker with local     user access via a side-channel analysis, aka     Speculative Store Bypass (SSB), Variant     4.(CVE-2018-3639)
