    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.
Comment 1 Christopher Díaz Riveros (RETIRED) gentoo-dev Security 2018-04-04 19:10:02 UTC
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.
