Notes

Title of the patch
Security update for the Linux Kernel (Live Patch 21 for SLE 12 SP1)
Description of the patch
This update for the Linux Kernel 3.12.74-60_64_60 fixes several issues. The following security issues were fixed: - CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c 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 (bsc#1069708). - CVE-2017-10661: Race condition in fs/timerfd.c allowed local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing (bsc#1053153).
