Almost unfixable “Sinkclose” bug affects hundreds of millions of AMD chips

Quick Summary:

IOActive's researchers warn that it affects virtually all AMD chips dating back to 2006, or possibly even earlier.

But only rarely does that kind of vulnerability appear not in the firmware of any particular computer maker, but in the chips found across hundreds of millions of PCs and servers.

The flaw would allow hackers to run their own code in one of the most privileged modes of an AMD processor, known as System Management Mode, designed to be reserved only for a specific, protected portion of its firmware.
