Description Prasad J Pandit 2013-07-23 15:13:39 EDT
Linux kernel built with IPv6 networking is vulnerable to a crash while sending
data as a single datagram over IPv6 socket when UDP_CORK option set. UDP_CORK
enables accumulating data and sending it as a single datagram.

An unprivileged user/program could use this flaw to crash the kernel, resulting in local DoS.
