"The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
security and bugfixes. The following security bugs were fixed :

  - CVE-2018-3620: Local attackers on baremetal systems
    could use speculative code patterns on hyperthreaded
    processors to read data present in the L1 Datacache used
    by other hyperthreads on the same CPU core, potentially
    leaking sensitive data. (bnc#1087081).

  - CVE-2018-3646: Local attackers in virtualized guest
    systems could use speculative code patterns on
    hyperthreaded processors to read data present in the L1
    Datacache used by other hyperthreads on the same CPU
    core, potentially leaking sensitive data, even from
    other virtual machines or the host system.
    (bnc#1089343).

  - CVE-2018-1000204: A malformed SG_IO ioctl issued for a
    SCSI device could lead to a local kernel information
    leak manifesting in up to approximately 1000 memory
    pages copied to the userspace. The problem has limited
    scope as non-privileged users usually have no
    permissions to access SCSI device files. (bnc#1096728).

  - CVE-2018-13053: The alarm_timer_nsleep function in
    kernel/time/alarmtimer.c had an integer overflow via a
    large relative timeout because ktime_add_safe is not
    used (bnc#1099924).

  - CVE-2018-13406: An integer overflow in the
    uvesafb_setcmap function in
    drivers/video/fbdev/uvesafb.c could result in local
    attackers being able to crash the kernel or potentially
    elevate privileges because kmalloc_array is not used
    (bnc#1098016 bnc#1100418).

  - CVE-2016-8405: An information disclosure vulnerability
    in kernel components including the ION subsystem,
    Binder, USB driver and networking subsystem could enable
    a local malicious application to access data outside of
    its permission levels. (bnc#1099942).

  - CVE-2018-5814: Multiple race condition errors when
    handling probe, disconnect, and rebind operations could
    be exploited to trigger a use-after-free condition or a
    NULL pointer dereference by sending multiple USB over IP
    packets (bnc#1096480).

  - CVE-2018-12233: In the ea_get function in fs/jfs/xattr.c
    a memory corruption bug in JFS can be triggered by
    calling setxattr twice with two different extended
    attribute names on the same file. This vulnerability can
    be triggered by an unprivileged user with the ability to
    create files and execute programs. (bnc#1097234).

  - CVE-2017-13305: A information disclosure vulnerability
    in the Upstream kernel encrypted-keys. (bnc#1094353).

  - CVE-2018-1130: A NULL pointer dereference in
    dccp_write_xmit() function in net/dccp/output.c allowed
    a local user to cause a denial of service by a number of
    certain crafted system calls (bnc#1092904).

  - CVE-2018-1068: A flaw was found in the implementation of
    32-bit syscall interface for bridging. This allowed a
    privileged user to arbitrarily write to a limited range
    of kernel memory (bnc#1085107).

  - CVE-2018-5803: An error in the '_sctp_make_chunk()'
    function (net/sctp/sm_make_chunk.c) when handling SCTP
    packets length could be exploited to cause a kernel
    crash (bnc#1083900).

  - CVE-2018-7492: A NULL pointer dereference was found in
    the net/rds/rdma.c __rds_rdma_map() function allowed
    local attackers to cause a system panic and a
    denial-of-service, related to RDS_GET_MR and
    RDS_GET_MR_FOR_DEST (bnc#1082962).

The update package also includes non-security fixes. See advisory for
details.

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
