Another AMD Zen ‘Secure Encrypted Virtualization’ Vulnerability Demonstrated by Researchers

A team of security researchers with Cornell University have demonstrated a proof of concept attack on AMD’s Secure Encrypted Virtualization (SEV) technology, leveraging the Zen-integrated AMD Secure Processor (AMD-SP) to achieve full system access.  The technique requires physical access to the AMD system and is based on a voltage glitching attack that allows a bad…
