The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in
the Linux kernel before 3.12.8 on the AMD K7 and K8 platforms does not
clear pending exceptions before proceeding to an EMMS instruction, which
allows local users to cause a denial of service (task kill) or possibly
gain privileges via a crafted application.
