Revision 12176503366885edd542389eed3aaf94be163fdb authored by Kees Cook on 25 October 2012, 20:38:16 UTC, committed by Linus Torvalds on 25 October 2012, 21:37:53 UTC
The compat ioctl for VIDEO_SET_SPU_PALETTE was missing an error check
while converting ioctl arguments.  This could lead to leaking kernel
stack contents into userspace.

Patch extracted from existing fix in grsecurity.
