    "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 :
    
      - Array index error in the tcm_vhost_make_tpg function in
        drivers/vhost/scsi.c in the Linux kernel before 4.0
        might allow guest OS users to cause a denial of service
        (memory corruption) or possibly have unspecified other
        impact via a crafted VHOST_SCSI_SET_ENDPOINT ioctl
        call. NOTE: the affected function was renamed to
        vhost_scsi_make_tpg before the vulnerability was
        announced.(CVE-2015-4036i1/4%0
    
      - The llc_cmsg_rcv function in net/llc/af_llc.c in the
        Linux kernel before 4.5.5 does not initialize a certain
        data structure, which allows attackers to obtain
        sensitive information from kernel stack memory by
        reading a message.(CVE-2016-4485i1/4%0
    
      - The nr_recvmsg function in net/netrom/af_netrom.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-2013-7269i1/4%0
    
      - The mct_u232_msr_to_state function in
        drivers/usb/serial/mct_u232.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 USB device without two
        interrupt-in endpoint descriptors.(CVE-2016-3136i1/4%0
    
      - An out-of-bounds memory access flaw, CVE-2014-7825, was
        found in the syscall tracing functionality of the Linux
        kernel's perf subsystem. A local, unprivileged user
        could use this flaw to crash the system. Additionally,
        an out-of-bounds memory access flaw, CVE-2014-7826, was
        found in the syscall tracing functionality of the Linux
        kernel's ftrace subsystem. On a system with ftrace
        syscall tracing enabled, a local, unprivileged user
        could use this flaw to crash the system, or escalate
        their privileges.(CVE-2014-7826i1/4%0
    
      - Linux kernel built with the Kernel-based Virtual
        Machine (CONFIG_KVM) support is vulnerable to a null
        pointer dereference flaw. It could occur on x86
        platform, when emulating an undefined instruction. An
        attacker could use this flaw to crash the host kernel
        resulting in DoS.(CVE-2016-8630i1/4%0
    
      - A flaw was found in the Linux kernel's ext4 filesystem.
        A local user can cause an out-of-bound access in
        ext4_get_group_info function, a denial of service, and
        a system crash by mounting and operating on a crafted
        ext4 filesystem image.(CVE-2018-10881i1/4%0
    
      - The arch_timer_reg_read_stable macro in
        arch/arm64/include/asm/arch_timer.h in the Linux kernel
        before 4.13 allows local users to cause a denial of
        service (infinite recursion) by writing to a file under
        /sys/kernel/debug in certain circumstances, as
        demonstrated by a scenario involving debugfs, ftrace,
        PREEMPT_TRACER, and
        FUNCTION_GRAPH_TRACER.(CVE-2017-18261i1/4%0
    
      - The ip6_route_add function in net/ipv6/route.c in the
        Linux kernel through 3.13.6 does not properly count the
        addition of routes, which allows remote attackers to
        cause a denial of service (memory consumption) via a
        flood of ICMPv6 Router Advertisement
        packets.(CVE-2014-2309i1/4%0
    
      - In the Linux kernel before 4.20.2, kernel/sched/fair.c
        mishandles leaf cfs_rq's, which allows attackers to
        cause a denial of service (infinite loop in
        update_blocked_averages) or possibly have unspecified
        other impact by inducing a high load.(CVE-2018-20784i1/4%0
    
      - An issue was discovered in the F2FS filesystem code in
        fs/f2fs/inline.c in the Linux kernel. A denial of
        service due to the out-of-bounds memory access can
        occur for a modified f2fs filesystem
        image.(CVE-2018-13099i1/4%0
    
      - An out-of-bounds write vulnerability was found in the
        Linux kernel's vmw_surface_define_ioctl() function, in
        the 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file. Due
        to the nature of the flaw, privilege escalation cannot
        be fully ruled out, although we believe it is
        unlikely.(CVE-2017-7294i1/4%0
    
      - A flaw was found in the way the Linux kernel's KVM
        subsystem handled non-canonical addresses when
        emulating instructions that change the RIP (for
        example, branches or calls). A guest user with access
        to an I/O or MMIO region could use this flaw to crash
        the guest.(CVE-2014-3647i1/4%0
    
      - The __munlock_pagevec function in mm/mlock.c in the
        Linux kernel, before 4.11.4, allows local users to
        cause a denial of service (NR_MLOCK accounting
        corruption) via crafted use of mlockall and munlockall
        system calls.(CVE-2017-18221i1/4%0
    
      - ** RESERVED ** This candidate has been reserved by an
        organization or individual that will use it when
        announcing a new security problem. When the candidate
        has been publicized, the details for this candidate
        will be provided.(CVE-2018-1120i1/4%0
    
      - The proc_connectinfo() function in
        'drivers/usb/core/devio.c' in the Linux kernel through
        4.6 does not initialize a certain data structure, which
        allows local users to obtain sensitive information from
        kernel stack memory via a crafted USBDEVFS_CONNECTINFO
        ioctl call. The stack object 'ci' has a total size of 8
        bytes. Its last 3 bytes are padding bytes which are not
        initialized and are leaked to
        userland.(CVE-2016-4482i1/4%0
    
      - A vulnerability was found in the Linux kernel. An
        unprivileged local user could trigger oops in
        shash_async_export() by attempting to force the
        in-kernel hashing algorithms into decrypting an empty
        data set.(CVE-2016-8646i1/4%0
    
      - An issue was discovered in the btrfs filesystem code in
        the Linux kernel. An invalid NULL pointer dereference
        in btrfs_root_node() when mounting a crafted btrfs
        image is due to a lack of chunk block group mapping
        validation in btrfs_read_block_groups() in the
        fs/btrfs/extent-tree.c function and a lack of
        empty-tree checks in check_leaf() in
        fs/btrfs/tree-checker.c function. This could lead to a
        system crash and a denial of service.(CVE-2018-14612i1/4%0
    
      - It was found that the Linux kernel's TCP/IP protocol
        suite implementation for IPv6 allowed the Hop Limit
        value to be set to a smaller value than the default
        one. An attacker on a local network could use this flaw
        to prevent systems on that network from sending or
        receiving network packets.(CVE-2015-2922i1/4%0
    
      - A NULL-pointer dereference flaw was found in the
        kernel, which is caused by a race between revoking a
        user-type key and reading from it. The issue could be
        triggered by an unprivileged user with a local account,
        causing the kernel to crash (denial of
        service).(CVE-2015-7550i1/4%0

    descriptionUSN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update, a regression was introduced that caused a kernel crash when handling fragmented packets in some situations. This update addresses the issue. We apologize for the inconvenience. Original advisory details : Hui Peng and Mathias Payer discovered that the Option USB High Speed driver in the Linux kernel did not properly validate metadata received from the device. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2018-19985) Zhipeng Xie discovered that an infinite loop could triggered in the CFS Linux kernel process scheduler. A local attacker could possibly use this to cause a denial of service. (CVE-2018-20784) It was discovered that the Intel Wi-Fi device driver in the Linux kernel did not properly validate certain Tunneled Direct Link Setup (TDLS). A physically proximate attacker could use this to cause a denial of service (Wi-Fi disconnect). (CVE-2019-0136) It was discovered that the Bluetooth UART implementation in the Linux kernel did not properly check for missing tty operations. A local attacker could use this to cause a denial of service. (CVE-2019-10207) Amit Klein and Benny Pinkas discovered that the Linux kernel did not sufficiently randomize IP ID values generated for connectionless networking protocols. A remote attacker could use this to track particular Linux devices. (CVE-2019-10638) Amit Klein and Benny Pinkas discovered that the location of kernel addresses could be exposed by the implementation of connection-less network protocols in the Linux kernel. A remote attacker could possibly use this to assist in the exploitation of another vulnerability in the Linux kernel. (CVE-2019-10639) It was discovered that an integer overflow existed in the Linux kernel when reference counting pages, leading to potential use-after-free issues. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-11487) Jann Horn discovered that a race condition existed in the Linux kernel when performing core dumps. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2019-11599) It was discovered that a NULL pointer dereference vulnerability existed in the LSI Logic MegaRAID driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-11810) It was discovered that the GTCO tablet input driver in the Linux kernel did not properly bounds check the initial HID report sent by the device. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-13631) Praveen Pandey discovered that the Linux kernel did not properly validate sent signals in some situations on PowerPC systems with transactional memory disabled. A local attacker could use this to cause a denial of service. (CVE-2019-13648) It was discovered that the floppy driver in the Linux kernel did not properly validate meta data, leading to a buffer overread. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-14283) It was discovered that the floppy driver in the Linux kernel did not properly validate ioctl() calls, leading to a division-by-zero. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-14284) Tuba Yavuz discovered that a race condition existed in the DesignWare USB3 DRD Controller device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service. (CVE-2019-14763) It was discovered that an out-of-bounds read existed in the QLogic QEDI iSCSI Initiator Driver in the Linux kernel. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2019-15090) It was discovered that the Raremono AM/FM/SW radio device driver in the Linux kernel did not properly allocate memory, leading to a use-after-free. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2019-15211) It was discovered at a double-free error existed in the USB Rio 500 device driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service. (CVE-2019-15212) It was discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel, leading to a potential use-after-free. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-15214) It was discovered that a race condition existed in the CPiA2 video4linux device driver for the Linux kernel, leading to a use-after-free. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-15215) It was discovered that a race condition existed in the Softmac USB Prism54 device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15220) It was discovered that a use-after-free vulnerability existed in the AppleTalk implementation in the Linux kernel if an error occurs during initialization. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-15292) Jason Wang discovered that an infinite loop vulnerability existed in the virtio net driver in the Linux kernel. A local attacker in a guest VM could possibly use this to cause a denial of service in the host system. (CVE-2019-3900) Daniele Antonioli, Nils Ole Tippenhauer, and Kasper B. Rasmussen discovered that the Bluetooth protocol BR/EDR specification did not properly require sufficiently strong encryption key lengths. A physically proximate attacker could use this to expose sensitive information. (CVE-2019-9506) It was discovered that a race condition existed in the USB YUREX device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15216) It was discovered that the Siano USB MDTV receiver device driver in the Linux kernel made improper assumptions about the device characteristics. A physically proximate attacker could use this cause a denial of service (system crash). (CVE-2019-15218) It was discovered that the Line 6 POD USB device driver in the Linux kernel did not properly validate data size information from the device. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15221) Muyu Yu discovered that the CAN implementation in the Linux kernel in some situations did not properly restrict the field size when processing outgoing frames. A local attacker with CAP_NET_ADMIN privileges could use this to execute arbitrary code. (CVE-2019-3701) Vladis Dronov discovered that the debug interface for the Linux kernel
