CVE-2014-1438: n/a vulnerability

CVE-2014-1438: The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8...

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.

Security readout for executives and security teams

This is an old Linux kernel flaw affecting AMD K7/K8 systems before kernel 3.12.8. A local user running a crafted application could cause denial of service by killing a task, and the CVE notes possible privilege gain. The evidence points to kernel and distribution updates as the remediation path. Exposure is likely limited to legacy Linux systems running kernels before 3.12.8 on AMD K7 or K8 processors. Internet-facing exposure is not indicated; local code execution appears required. Treat as a legacy local-risk issue. It is not a broad remote emergency, but any still-running vulnerable shared Linux host should be patched or retired because privilege escalation is noted as possible. Mitigation focus: Upgrade to a vendor kernel containing the CVE-2014-1438 fix.; Confirm Linux kernel is 3.12.8 or vendor-patched equivalent.; Prioritize systems allowing untrusted local users or shared shell access..
