  script_tag(name:"insight", value:"The openSUSE Leap 15.1 kernel was updated to receive various security and
  bugfixes.

  The following security bugs were fixed:

  - CVE-2019-0154: An unprotected read access to i915 registers has been
  fixed that could have been abused to facilitate a local
  denial-of-service attack.  (bsc#1135966)

  - CVE-2019-0155: A privilege escalation vulnerability has been fixed in
  the i915 module that allowed batch buffers from user mode to gain super
  user privileges. (bsc#1135967)

  - CVE-2019-16231: drivers/net/fjes/fjes_main.c did not check the
  alloc_workqueue return value, leading to a NULL pointer dereference
  (bnc#1150466).

  - CVE-2019-18805: There was a net/ipv4/tcp_input.c signed integer overflow
  in tcp_ack_update_rtt() when userspace writes a very large integer to
  /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or
  possibly unspecified other impact, aka CID-19fad20d15a6 (bnc#1156187).

  - CVE-2019-17055: base_sock_create in drivers/isdn/mISDN/socket.c in the
  AF_ISDN network module did not enforce CAP_NET_RAW, which means that
  unprivileged users can create a raw socket, aka CID-b91ee4aa2a21
  (bnc#1152782).

  - CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs
  with Transactional Memory support could be used to facilitate
  sidechannel information leaks out of microarchitectural buffers, similar
  to the previously described 'Microarchitectural Data Sampling' attack.

  The Linux kernel was supplemented with the option to disable TSX
  operation altogether (requiring CPU Microcode updates on older systems)
  and better flushing of microarchitectural buffers (VERW).

  - CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a
  race condition in the Instruction Fetch Unit of the Intel CPU to cause a
  Machine Exception during Page Size Change, causing the CPU core to be
  non-functional.

  The Linux Kernel kvm hypervisor was adjusted to avoid page size changes
  in executable pages by splitting / merging huge pages into small pages as
  needed.

  - CVE-2019-10220: Added sanity checks on the pathnames passed to the user
  space. (bsc#1144903).

  The following non-security bugs were fixed:

  - ALSA: bebob: Fix prototype of helper function to return negative value
  (bsc#1051510).
