AMD Acknowledges Newly Disclosed Flaws In Its Processors — Patches Coming Soon

AMD has acknowledged 13 critical vulnerabilities, and exploitable backdoors in its Ryzen and EPYC processors disclosed earlier by Israel-based CTS Labs and promised to roll out firmware patches for millions of affected devices ‘in the coming weeks.’
According to CTS-Labs researchers, critical vulnerabilities (RyzenFall, MasterKey, Fallout, and Chimera) that affect AMD’s Platform Security Processor (PSP) could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems.
Although exploiting AMD vulnerabilities require admin access, it could help attackers defeat important security features like Windows Credential Guard, TPMs, and virtualization that are responsible for preventing access to the sensitive data from even an admin or root account.
In a press release published by AMD, the company downplays the threat by saying that, “any attacker gaining unauthorized administrative access would have a wide range of attacks at their disposal well beyond the exploits identified in this research.”
