CVE-2009-1046 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1046):
  The console selection feature in the Linux kernel 2.6.28 before
  2.6.28.4, 2.6.25, and possibly earlier versions, when the UTF-8
  console is used, allows physically proximate attackers to cause a
  denial of service (memory corruption) by selecting a small number of
  3-byte UTF-8 characters, which triggers an "an off-by-two memory
  error." NOTE: it is not clear whether this issue crosses privilege
  boundaries.
