Security update for the Linux Kernel (important)

The openSUSE Leap 42.3 kernel was updated to receive various security and
bugfixes.

The following security bugs were fixed:

• CVE-2017-1000111: Fixed a race condition in net-packet code that could
  be exploited to cause out-of-bounds memory access (bsc#1052365).
• CVE-2017-1000112: Fixed a race condition in net-packet code that could
  have been exploited by unprivileged users to gain root access.
  (bsc#1052311).
• CVE-2017-8831: The saa7164_bus_get function in
  drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel allowed
  local users to cause a denial of service (out-of-bounds array access) or
  possibly have unspecified other impact by changing a certain
  sequence-number value, aka a "double fetch" vulnerability (bnc#1037994).
