The dccp_rcv_state_process function in net/dccp/input.c in the Datagram
Congestion Control Protocol (DCCP) implementation in the Linux kernel
before 2.6.38 does not properly handle packets for a CLOSED endpoint, which
allows remote attackers to cause a denial of service (NULL pointer
dereference and OOPS) by sending a DCCP-Close packet followed by a
DCCP-Reset packet.
