"This update for the Linux Kernel 3.12.61-52_122 fixes several issues.
The following security issue was 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)
