AMD investigating major security flaws in Ryzen chips

AMD investigating major security flaws in Ryzen chips

CTS-Labs, an Israeli cybersecurity firm, says it has found multiple flaws in AMD's RYZEN and EPYC processors that could let hackers who've already compromised computers access secure portions of the processors to install malware or steal sensitive data like encryption keys.

The 13 vulnerabilities listed in the white paper allegedly affect all Ryzen and Ryzen Pro products now on the market, as well as EPYC server CPUs made by AMD, but do require root-level (administrator) operating-system access in order to exploit.

CTS has classified the vulnerabilities, which it found over the course of a six-month investigation, into four categories they're calling Ryzenfall, Masterkey, Fallout and Chimera.

As reported by CNET, the researchers gave AMD a 24 Hour window to take a look at the Spectre-like vulnerabilities which is an unusual move as usually security firms give companies a few months before they publish their report.

This means that AMD-powered PCs are vulnerable to these hacks starting now, through to when the company can fix it.

AMD responded to the CTS Labs report, stating that it is investigating and analysing the findings.

"At AMD, security is a top priority and we are continually working to ensure the safety of our users as potential new risks arise".
