A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.
TridentStack Control can deploy fixes like this automatically across your Windows, macOS, and Linux fleet. See how it works
