Vulnerability from fkie_nvd - Published: 2014-01-18 22:55 - Updated: 2026-06-17 00:04
Severity
Summary
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.
