AMD admits Zen 3 processors are vulnerable to Spectre-like side-channel attack – TechRadar
Team Red’s PSF feature can be exploited by hackers
AMD has admitted that Zen 3 processors, such as the Ryzen 5000 CPU series, are vulnerable to a side-channel exploit thats similar to the Spectre flaw that previously impacted a number of Intel processors.
The vulnerability relates to a new feature AMD introduced with Zen 3 called Predictive Store Forwarding (PSF), which is hardware-based micro-architectural optimization designed to improve the performance of code execution by predicting dependencies between loads and stores.
“In typical code, PSF…
