CVE-2011-1776 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1776):
  The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel before
  2.6.39 does not check the size of an Extensible Firmware Interface (EFI)
  GUID Partition Table (GPT) entry, which allows physically proximate
  attackers to cause a denial of service (heap-based buffer overflow and OOPS)
  or obtain sensitive information from kernel heap memory by connecting a
  crafted GPT storage device, a different vulnerability than CVE-2011-1577.
