  security and bugfixes.

  Four new speculative execution information leak issues have been
  identified in Intel CPUs. (bsc#1111331)

  - CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS)

  - CVE-2018-12127: Microarchitectural Fill Buffer Data Sampling (MFBDS)

  - CVE-2018-12130: Microarchitectural Load Port Data Sampling (MLPDS)

  - CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory
  (MDSUM)

  This kernel update contains software mitigations for these issues, which
  also utilize CPU microcode updates shipped in parallel.

  The following security bugs were fixed:

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

  - CVE-2018-10853: A flaw was found in the way Linux kernel KVM hypervisor
  emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check
  current privilege(CPL) level while emulating unprivileged instructions.
  An unprivileged guest user/process could use this flaw to potentially
  escalate privileges inside guest (bnc#1097104).

  - CVE-2018-15594: arch/x86/kernel/paravirt.c in the Linux kernel
  mishandled certain indirect calls, which made it easier for attackers to
  conduct Spectre-v2 attacks against paravirtual guests (bnc#1105348
  1119974).

  - CVE-2018-17972: An issue was discovered in the proc_pid_stack function
  in fs/proc/base.c that did not ensure that only root may inspect the
  kernel stack of an arbitrary task, allowing a local attacker to exploit
  racy stack unwinding and leak kernel task stack contents (bnc#1110785).

  - CVE-2018-1000204: Prevent infoleak caused by incorrect handling of the
  SG_IO ioctl (bsc#1096728)

  - CVE-2019-11486: The Siemens R3964 line discipline driver in
  drivers/tty/n_r3964.c had multiple race conditions (bnc#1133188). It has
  been disabled.

  - CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in
  net/rds/tcp.c, a race condition leading to a use-after-free was fixed,
  related to net namespace cleanup (bnc#1134537).

  - CVE-2019-11884: The do_hidp_sock_ioctl function in
  net/bluetooth/hidp/sock.c allowed a local user to obtain potentially
  sensitive information from kernel stack memory via a HIDPCONNADD
