This update for the Linux Kernel 4.4.21-69 fixes several issues.

The following security bugs were fixed:

– CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not
consider the case of a NULL payload in conjunction with a nonzero length
value, which allowed local users to cause a denial of service (NULL
pointer dereference and OOPS) via a crafted add_key or keyctl system
call (bsc#1062471).
– CVE-2017-1000251: The native Bluetooth stack in the Linux Kernel (BlueZ)
was vulnerable to a stack overflow vulnerability in the processing of
L2CAP configuration responses resulting in Remote code execution in
kernel space (bsc#1057950).
– CVE-2017-12762: In drivers/isdn/i4l/isdn_net.c a user-controlled buffer
was copied into a local buffer of constant size using strcpy without a
length check which can cause a buffer overflow (bsc#1053150).
