Improper signature verification in AMD CPU ROM microcode patch loader may allow an attacker with local administrator privilege to load malicious microcode, potentially resulting in loss of integrity of x86 instruction execution, loss of confidentiality and integrity of data in x86 CPU privileged context and compromise of SMM execution environment.

Improper input validation in the SMM handler may allow a privileged attacker to overwrite SMRAM, potentially leading to arbitrary code execution.

Improper access control in the ASP could allow a privileged attacker to perform an out-of-bounds write to a memory location not controlled by the attacker, potentially leading to loss of confidentiality, integrity, or availability.

Improper input validation in the SMM handler may allow a privileged attacker to overwrite SMRAM, potentially leading to arbitrary code execution.
