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.
An attacker with specialized hardware and physical access to an impacted device may be able to perform a voltage fault injection attack resulting in compromise of the ASP secure boot potentially leading to arbitrary code execution.Â
Insufficient input validation in
CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting
an arbitrary bit in an attacker-controlled pointer potentially leading to
arbitrary code execution in SMM.
