    Description:


    The SUSE Linux Enterprise 12 kernel was updated to fix the following
    security bugs:

    - CVE-2017-7184: The Linux kernel allowed local users to obtain root
    privileges or cause a denial of service (heap-based out-of-bounds
    access) via unspecified vectors, as demonstrated during a Pwn2Own
    competition at CanSecWest 2017 (bnc#1030573, bnc#1028372).
    - CVE-2017-2636: Race condition in drivers/tty/n_hdlc.c in the Linux
    kernel allowed local users to gain privileges or cause a denial of
    service (double free) by setting the HDLC line discipline (bnc#1027565).
