   SUSE Security Update: Security update for the Linux Kernel (Live Patch 30 for SLE 12)

Announcement ID:    SUSE-SU-2018:0233-1
Rating:             important
References:         #1064388 #1064392 
Cross-References:   CVE-2017-15649
Affected Products:
                    SUSE Linux Enterprise Server 12-LTSS

   An update that solves one vulnerability and has one errata
   is now available.


   This update for the Linux Kernel 3.12.61-52_111 fixes one issue.

   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. This fixes the earlier kgraft update, that could have
     caused crashes when trying to exploit this vulnerability after applying
     the kgraft update (bsc#1064392, bsc#1064388).
