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.
