AMD admits Ryzen 5000 CPU exploit could leave your PC open to hackers

AMD’s Zen 3 CPU architecture may, according to AMD itself, include a feature that could be exploited by hackers in a Spectre-like side channel attack.

The speculative execution feature—which is a common feature in modern processors— is known as Predictive Store Forwarding (PSF) with Zen 3. Essentially its job is to guess which instruction is most likely to be sent next through the use of branch prediction algorithms, and fetch that command in anticipation. The point is to speed up the performance pipeline within the microprocessor but, as reported by TechPowerUp, the feature comes with its risks.
