Amd: >> Ryzen 3 5300g Firmware Security Vulnerabilities
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.

Insufficient bounds checking in ASP may allow an
attacker to issue a system call from a compromised ABL which may cause
arbitrary memory values to be initialized to zero, potentially leading to a
loss of integrity.

Certain size values in firmware binary headers
could trigger out of bounds reads during signature validation, leading to
denial of service or potentially limited leakage of information about
out-of-bounds memory contents.
