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).
