CVE-2014-1438  (opens in a new tab)
CWE-264  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 3.12.8 or higher.

Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. 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.
