Description (CNA)
Missing lock bit protection for NBIO registers could allow a local admin-privileged attacker to gain arbitrary System Management Network (SMN) access, potentially resulting in arbitrary code execution in AMD Secure Processor (ASP) and loss of the SEV-SNP guest's confidentiality and integrity.
