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 ims_pcu_get_cdc_union_desc function in     drivers/input/misc/ims-pcu.c in the Linux kernel,     through 4.13.11, allows local users to cause a denial     of service (ims_pcu_parse_cdc_data out-of-bounds read     and system crash) or possibly have unspecified other     impact via a crafted USB device.(CVE-2017-16645i1/4%0

  - It was found that due to excessive files_lock locking,     a soft lockup could be triggered in the Linux kernel     when performing asynchronous I/O operations. A local,     unprivileged user could use this flaw to crash the     system.(CVE-2014-8172i1/4%0

  - A flaw was discovered in the kernel's collect_mounts     function. If the kernel's audit subsystem called     collect_mounts to audit an unmounted path, it could     panic the system. With this flaw, an unprivileged user     could call umount(MNT_DETACH) to launch a     denial-of-service attack.(CVE-2015-4177i1/4%0

  - A flaw was found in the way the Linux kernel's floppy     driver handled user space provided data in certain     error code paths while processing FDRAWCMD IOCTL     commands. A local user with write access to /dev/fdX     could use this flaw to free (using the kfree()     function) arbitrary kernel memory. (CVE-2014-1737,     Important) was found that the Linux kernel's floppy     driver leaked internal kernel memory addresses to user     space during the processing of the FDRAWCMD IOCTL     command. A local user with write access to /dev/fdX     could use this flaw to obtain information about the     kernel heap arrangement. (CVE-2014-1738, Low)Note: A     local user with write access to /dev/fdX could use     these two flaws (CVE-2014-1737 in combination with     CVE-2014-1738) to escalate their privileges on the     system.(CVE-2014-1738i1/4%0

  - A reference counter leak in Linux kernel in     ipxitf_ioctl function was found which results in a use     after free vulnerability that's triggerable from     unprivileged userspace when IPX interface is     configured.(CVE-2017-7487i1/4%0

  - The x25_recvmsg function in net/x25/af_x25.c in the     Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7271i1/4%0

  - An inode data validation error was found in Linux     kernels built with UDF file system (CONFIG_UDF_FS)     support. An attacker able to mount a     corrupted/malicious UDF file system image could cause     the kernel to crash.(CVE-2015-4167i1/4%0

  - Double free vulnerability in the ioctx_alloc function     in fs/aio.c in the Linux kernel before 3.12.4 allows     local users to cause a denial of service (system crash)     or possibly have unspecified other impact via vectors     involving an error condition in the aio_setup_ring     function.(CVE-2013-7348i1/4%0

  - A flaw was found in the Linux kernel's implementation     of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt()     system call. Users with non-namespace CAP_NET_ADMIN are     able to trigger this call and create a situation in     which the sockets sendbuff data size could be negative.
    This could adversely affect memory allocations and     create situations where the system could crash or cause     memory corruption.(CVE-2016-9793i1/4%0

  - Use-after-free vulnerability in the     ffs_user_copy_worker function in     drivers/usb/gadget/function/f_fs.c in the Linux kernel     before 4.5.3 allows local users to gain privileges by     accessing an I/O data structure after a certain     callback call. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.(CVE-2016-7912i1/4%0

  - A flaw was found in the way the get_dumpable() function     return value was interpreted in the ptrace subsystem of     the Linux kernel. When 'fs.suid_dumpable' was set to 2,     a local, unprivileged local user could use this flaw to     bypass intended ptrace restrictions and obtain     potentially sensitive information.(CVE-2013-2929i1/4%0

  - A DoS flaw was found for a Linux kernel built for the     x86 architecture which had the KVM virtualization     support(CONFIG_KVM) enabled. The kernel would be     vulnerable to a NULL pointer dereference flaw in Linux     kernel's kvm_apic_has_events() function while doing an     ioctl. An unprivileged user able to access the     '/dev/kvm' device could use this flaw to crash the     system kernel.(CVE-2015-4692i1/4%0

  - The intr function in sound/oss/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-2017-9986i1/4%0

  - sound/soc/msm/qdsp6v2/msm-audio-effects-q6-v2.c in the     MSM QDSP6 audio 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 (buffer     over-read) or possibly have unspecified other impact     via a crafted application that makes an ioctl call     specifying many commands.(CVE-2016-2064i1/4%0

  - The digi_port_init function in     drivers/usb/serial/digi_acceleport.c in the Linux     kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (NULL pointer     dereference and system crash) via a crafted endpoints     value in a USB device descriptor.(CVE-2016-3140i1/4%0

  - In the Linux kernel through 4.14.13, the     rds_cmsg_atomic function in net/rds/rdma.c mishandles     cases where page pinning fails or an invalid address is     supplied, leading to an rds_atomic_free_op NULL pointer     dereference.(CVE-2018-5333i1/4%0

  - Multiple buffer underflows in the XFS implementation in     the Linux kernel through 3.12.1 allow local users to     cause a denial of service (memory corruption) or     possibly have unspecified other impact by leveraging     the CAP_SYS_ADMIN capability for a (1)     XFS_IOC_ATTRLIST_BY_HANDLE or (2)     XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted     length value, related to the xfs_attrlist_by_handle     function in fs/xfs/xfs_ioctl.c and the     xfs_compat_attrlist_by_handle function in     fs/xfs/xfs_ioctl32.c.(CVE-2013-6382i1/4%0

  - In the Linux kernel through 5.0.2, the function     inotify_update_existing_watch() in     fs/notify/inotify/inotify_user.c neglects to call     fsnotify_put_mark() with IN_MASK_CREATE after     fsnotify_find_mark(), which will cause a memory leak     (aka refcount leak). Finally, this will cause a denial     of service.(CVE-2019-9857i1/4%0

  - It was found that stacking a file system over procfs in     the Linux kernel could lead to a kernel stack overflow     due to deep nesting, as demonstrated by mounting     ecryptfs over procfs and creating a recursion by     mapping /proc/environ. An unprivileged, local user     could potentially use this flaw to escalate their     privileges on the system.(CVE-2016-1583i1/4%0

  - A heap-based buffer overflow vulnerability was found in     the Linux kernel's hiddev driver. This flaw could allow     a local attacker to corrupt kernel memory, possible     privilege escalation or crashing the     system.(CVE-2016-5829i1/4%0
