CVE-2011-1093 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1093):
  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.
