The following security issues were fixed:
- CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346 (bsc#1064392)

The following bugs were fixed:
- CVE-2017-1000364: The previous fix for the stack gap increase tracked by CVE-2017-1000364 had a regression, which is fixed by this follow up patch. (bsc#1039496)
The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-1000364: The default stack guard page was too small and could be 'jumped over' by userland programs using
more than one page of stack in functions and so lead to memory corruption. This update extends the stack guard page
to 1 MB (for 4k pages) and 16 MB (for 64k pages) to reduce this attack vector. This is not a kernel bugfix, but a
hardening measure against this kind of userland attack.(bsc#1039348)
