Description:
This update for the Linux Kernel 4.4.21-69 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).
- A stability issue in the btrfs module was fixed (bsc#1008284)
