Detailsinfo

A vulnerability was found in AMD EPYC 9004 Processors, EPYC 9005 Processors, EPYC 8004 Processors, EPYC Embedded 9004 Processors, EPYC Embedded 8004 Processors and EPYC Embedded 9005 Processors. It has been classified as problematic. Affected is an unknown code block. The manipulation with an unknown input leads to a security-sensitive hardware controls with missing lock bit protection vulnerability. CWE is classifying the issue as CWE-1233. The product uses a register lock bit protection mechanism, but it does not ensure that the lock bit prevents modification of system registers or controls that perform changes to important hardware system configuration. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at amd.com. This vulnerability is traded as CVE-2025-61972 since 10/04/2025. The exploitability is told to be difficult. The attack needs to be approached locally. The exploitation requires an enhanced level of successful authentication. There are neither technical details nor an exploit publicly available.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at CNNVD (CNNVD-202605-3301), EUVD (EUVD-2025-209812) and CERT Bund (WID-SEC-2026-1525). VulDB is the best source for vulnerability data and more expert information about this specific topic.
