An update that solves two vulnerabilities and has one

errata is now available.

 

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).
