From $URL : https://github.com/torvalds/linux/commit/12176503366885edd542389eed3aaf94be163fdb commit 12176503366885edd542389eed3aaf94be163fdb Author: Kees Cook <keescook@...omium.org> Date: Thu Oct 25 13:38:16 2012 -0700 fs/compat_ioctl.c: VIDEO_SET_SPU_PALETTE missing error check 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.
There are no longer any 2.x or <3.6.5 kernels available in the repository with the exception of sys-kernel/xbox-sources which is unsupported by security.
