Security update for Linux Kernel Live Patch 16 for SLE 12

Notes

Title of the patch
Security update for Linux Kernel Live Patch 16 for SLE 12
Description of the patch
This update for the Linux Kernel 3.12.60-52_57 fixes several issues. The following security bugs were fixed: - CVE-2016-8655: A race condition in the af_packet packet_set_ring function could be used by local attackers to crash the kernel or gain privileges (bsc#1012759). - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacks chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bsc#1012183).
