    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).
