SUSE-SU-2017:3286-1

This update for the Linux Kernel 4.4.59-92_20 fixes several issues.

The following security issues were fixed:

• CVE-2017-1000405: Problematic use of pmdmkdirty() in the touchpmd() function allowed users to overwrite read-only huge pages (e.g. the zero huge page and sealed shmem files) (bsc#1070307).
• CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrmuser.c kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SORCVBUF setsockopt system call in conjunction with XFRMMSGGETPOLICY 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).

This non-security issue was fixed:

• bsc#1062847: Enable proper shut down if NIC teaming is enabled
