CVE-2014-1438
Last modified
CVE-2014-1438 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.65% chance of exploitation in the next 30 days.
