CVE-2015-2922 (retired)

Priority
Description
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.
Ubuntu-Description
It was discovered that the Linux kernel's IPv6 networking stack has a flaw
that allows using route advertisement (RA) messages to set the 'hop_limit'
to values that are too low. An unprivileged attacker on a local network
could exploit this flaw to cause a denial of service (IPv6 messages
dropped).
