Detailsinfo

A vulnerability was found in AMD EPYC 9005 Processors, EPYC 8005 Processors and EPYC Embedded 9005 Processors (the affected version unknown). It has been rated as problematic. Affected by this issue is an unknown part of the component Secure Encrypted Virtualization. The manipulation with an unknown input leads to a use after free vulnerability. Using CWE to declare the problem leads to CWE-416. The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Operation on a resource after expiration or release in the AMD Secure Encrypted Virtualization (SEV) firmware could allow an attacker with administrative privileges to swap out a guest device without the guest's knowledge, potentially resulting in a loss of confidentiality and integrity.

The advisory is available at amd.com. This vulnerability is handled as CVE-2026-0435 since 12/06/2025. The exploitation is known to be easy. The attack may be launched remotely. Additional levels of successful authentication are necessary for exploitation. The technical details are unknown and an exploit is not available.
