CVE-2025-61972
Last modified
CVE-2025-61972 is a high-severity vulnerability rated 8.5/10 on the CVSS scale. 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.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
Description
