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.

CVE-2014-1438 kernel: x86: exceptions are not cleared in AMD FXSAVE workaround
Linux kernel is found to be vulnerable to a NULL pointer dereference flaw
caused due to inappropriate handling of Floating Point Unit(FPU) exceptions
during task switch at 'emms' instruction. This only affects AMD CPU family
in both i386 & AMD64 modes.
A user/program could use this flaw to kill tasks at random resulting in DoS
or potentially gain root privileges if allowed to map NULL(mmap_min_addr=0)
page.
