CVE-2009-3002 (
  The Linux kernel before 2.6.31-rc7 does not initialize certain data
  structures within getname functions, which allows local users to read
  the contents of some kernel memory locations by calling getsockname
  on (1) an AF_APPLETALK socket, related to the atalk_getname function
  in net/appletalk/ddp.c; (2) an AF_IRDA socket, related to the
  irda_getname function in net/irda/af_irda.c; (3) an AF_ECONET socket,
  related to the econet_getname function in net/econet/af_econet.c; (4)
  an AF_NETROM socket, related to the nr_getname function in
  net/netrom/af_netrom.c; (5) an AF_ROSE socket, related to the
  rose_getname function in net/rose/af_rose.c; or (6) a raw CAN socket,
  related to the raw_getname function in net/can/raw.c.
