Key facts

Description

Heap-based buffer overflow in the is_gpt_valid function in fs/partitions/efi.c in the Linux kernel 2.6.38 and earlier allows physically proximate attackers to cause a denial of service (OOPS) or possibly have unspecified other impact via a crafted size of the EFI GUID partition-table header on removable media.
