CVE-2009-2698 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-2698):
  The UDP implementation in (1) net/ipv4/udp.c and (2) net/ipv6/udp.c
  in the Linux kernel before 2.6.19 allows local users to gain
  privileges or cause a denial of service (NULL pointer dereference and
  system crash) via vectors involving the MSG_MORE flag and a UDP
  socket.
