CVE-2025-54501 · Severity: info · Published 2026-11-12

AMD EPYC processors contain an improperly secured debug interface that could allow a privileged attacker to bypass memory access controls. An exploit could compromise the integrity of SEV-SNP guest virtual machine memory, potentially exposing sensitive data or enabling unauthorized modifications within isolated security domains.

Vendors: [Amd](https://junglewise.ai/threats/vendors/amd).

## Technical details

An internal debug interface in AMD EPYC processors lacks adequate access control, allowing a high-privileged attacker to circumvent SEV-SNP (Secure Encrypted Virtualization-Secure Nested Paging) memory isolation protections. The vulnerability requires elevated privileges to exploit but could result in unauthorized memory access or modification within guest VMs. No public exploit has been confirmed.
