Researchers discover potentially catastrophic exploit present in AMD chips for decades

Researchers discovered a potentially catastrophic vulnerability in AMD chips that has been there for decades. It’s called a ‘Sinkclose’ flaw.

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. That’s a lot of work for a random home PC, phew, but could spell trouble for corporations or other large entities. It compares using the Sinkclose flaw to accessing a bank’s safe-deposit boxes after already bypassing alarms, guards, vault doors and other security measures.
