* CVE-2015-3636: Memory corruption when unhashing IPv4 ping sockets.
The kernel IPv4 subsystem does not correctly handle unhashing a ping
socket which can trigger kernel memory corruption. A local user can use
this flaw to gain elevated privileges.
* CVE-2015-2922: Denial-of-service of IPv6 networks when handling router advertisements.
A flaw in the IPv6 stack allowed a remote attacker on the same network to
set the hop limit to a smaller value than the default one, preventing
devices on that network to send or receive.
