   An update that solves two vulnerabilities and has one
   errata is now available.

Description:



   The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2017-1000405: A bug in the THP CoW support could be used by local
     attackers to corrupt memory of other processes and cause them to crash
     (bnc#1069496).
   - CVE-2017-16939: The XFRM dump policy implementation in
     net/xfrm/xfrm_user.c in the Linux kernel allowed local users to gain
     privileges or cause a denial of service (use-after-free) via a crafted
     SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY
     Netlink messages (bnc#1069702).

   The following non-security bugs were fixed:

   Fix a build issue on ppc64le systems (bsc#1070805)
