CVE-2009-1192 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1192):
  drivers/char/agp/generic.c in the agp subsystem in the Linux kernel
  before 2.6.30-rc3 does not zero out pages that may later be available
  to a user-space process, which allows local users to obtain sensitive
  information by reading these pages.
