A potential vulnerability exists in AMD Platform Security Processor (PSP) that may allow an attacker to zero any privileged register on the System Management Network which may lead to bypassing SPI ROM protections.

A side effect of an integrated chipset option may be able to be used by an attacker to bypass SPI ROM protections, allowing unauthorized SPI ROM modification.

Race condition in ASP firmware could allow less privileged x86 code to perform ASP SMM (System Management Mode) operations.
