"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

  - CVE-2014-9940
    A use-after-free flaw in the voltage and current
    regulator driver could allow a local user to cause a
    denial of service or potentially escalate privileges.

  - CVE-2017-7346
    Li Qiang discovered that the DRM driver for VMware
    virtual GPUs does not properly check user-controlled
    values in the vmw_surface_define_ioctl() functions for
    upper limits. A local user can take advantage of this
    flaw to cause a denial of service.

  - CVE-2017-7482
    Shi Lei discovered that RxRPC Kerberos 5 ticket handling
    code does not properly verify metadata, leading to
    information disclosure, denial of service or potentially
    execution of arbitrary code.

  - CVE-2017-7533
    Fan Wu and Shixiong Zhao discovered a race condition
    between inotify events and VFS rename operations
    allowing an unprivileged local attacker to cause a
    denial of service or escalate privileges.

  - CVE-2017-7541
    A buffer overflow flaw in the Broadcom IEEE802.11n PCIe
    SoftMAC WLAN driver could allow a local user to cause
    kernel memory corruption, leading to a denial of service
    or potentially privilege escalation.

  - CVE-2017-7542
    An integer overflow vulnerability in the
    ip6_find_1stfragopt() function was found allowing a
    local attacker with privileges to open raw sockets to
    cause a denial of service.

  - CVE-2017-7889
    Tommi Rantala and Brad Spengler reported that the mm
    subsystem does not properly enforce the
    CONFIG_STRICT_DEVMEM protection mechanism, allowing a
    local attacker with access to /dev/mem to obtain
    sensitive information or potentially execute arbitrary
    code.

  - CVE-2017-9605
    Murray McAllister discovered that the DRM driver for
    VMware virtual GPUs does not properly initialize memory,
    potentially allowing a local attacker to obtain
    sensitive information from uninitialized kernel memory
    via a crafted ioctl call.

  - CVE-2017-10911
    / XSA-216

  Anthony Perard of Citrix discovered an information leak flaw in Xen
  blkif response handling, allowing a malicious unprivileged guest to
  obtain sensitive information from the host or other guests.

  - CVE-2017-11176
    It was discovered that the mq_notify() function does not
    set the sock pointer to NULL upon entry into the retry
    logic. An attacker can take advantage of this flaw
    during a userspace close of a Netlink socket to cause a
    denial of service or potentially cause other impact.

  - CVE-2017-1000363
    Roee Hay reported that the lp driver does not properly
    bounds-check passed arguments, allowing a local attacker
    with write access to the kernel command line arguments
    to execute arbitrary code.

  - CVE-2017-1000365
    It was discovered that argument and environment pointers
    are not taken properly into account to the imposed size
    restrictions on arguments and environmental strings
    passed through RLIMIT_STACK/RLIMIT_INFINITY. A local
    attacker can take advantage of this flaw in conjunction
    with other flaws to execute arbitrary code."
