An update that solves two vulnerabilities and has one security fix can now be installed.

Description:

The SUSE Linux Enterprise 12 SP2 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)
