CVE-2009-3043 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3043):
  The tty_ldisc_hangup function in drivers/char/tty_ldisc.c in the
  Linux kernel before 2.6.31-rc8 allows local users to cause a denial
  of service (system crash, sometimes preceded by a NULL pointer
  dereference) or possibly gain privileges via certain pseudo-terminal
  I/O activity, as demonstrated by KernelTtyTest.c.
