Subject: CVE request: kernel: validate size of EFI GUID partition entries

The kernel automatically evaluates partition tables of storage devices. 
The code for evaluating GUID partitions (in fs/partitions/efi.c) 
contains a bug that can cause a kernel heap overflow on certain 
corrupted GUID partition tables.
