CVE-2014-1438

Linux Kernel < 3.12.8 - Denial of Service via FPU Exception Handling

Title source: llm
STIX 2.1

Description

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.
