AMD has found a vulnerability in its latest Ryzen processors, but claims not to worry

Published

on

Several years ago, there was a boom in the detection of vulnerabilities in the processor market, which has already been safely forgotten. More often, vulnerabilities were found in Intel CPUs, while AMD processors did not.

Now AMD itself has found a new vulnerability in its new generation Ryzen processors. It allows the use of so-called side-channel or side-channel attacks. This kind of attack is similar to the one underlying the Specter vulnerability.

The vulnerability was found in the latest Zen 3 architecture. More precisely, the reason is the new Predictive Store Forwarding (PSF) function, which is a predictor of the result of loading instructions. In most cases, the PSF forecast comes true, which allows Ryzen processors to execute instructions in advance that would normally be executed much later.

However, there are times when the predictor is wrong. In this case, the very vulnerability is formed. AMD itself has no evidence of anyone ever exploiting this vulnerability and considers the risks to be low. The company has explained how to disable PSF, but warns that it will negatively impact performance. It is possible that AMD is already working on a patch to fix the discovered vulnerability.
