	Enea Linux Security Advisory

Product/package: kernel (linux-qoriq 3.12) /Enea Linux 5.0
Severity: Low
CVE Name: CVE-2015-2922, kernel-ipv6
Layer: meta-enea

This update fixes denial of service (DoS) attack against IPv6 network
stacks due to improper handling of Router Advertisements.

The ndisc_router_discovery function in net/ipv6/ndisc.c in the Neighbor
Discovery (ND) protocol implementation in the IPv6 stack in the Linux
kernel before 3.19.6 allows remote attackers to reconfigure a hop-limit
setting via a small hop_limit value in a Router Advertisement (RA) message.
