Researchers discover potentially catastrophic exploit present in AMD chips for decades

Security researchers have found a vulnerability in AMD processors that has persisted for decades, according to reporting by Wired. This is a fascinating security flaw because it was found in the firmware of the actual chips and potentially allows malware to deeply infect a computer’s memory.

The flaw was discovered by researchers from the security firm IOActive, who are calling the AMD-based vulnerability a “Sinkclose" flaw. This potentially allows hackers to run their own code in the most privileged mode of an AMD processor, System Management Mode. This is typically a protected portion of the firmware. The researchers have also noted that the flaw dates back to at least 2006 and that it impacts nearly every AMD chip.
