Doc Text:
A flaw was found in asp-bootloader, the AMD Secure Processor bootloader. The use of a static cryptographic key per device allows a local attacker with administrative privileges to downgrade the Secure Encrypted Virtualization (SEV) firmware. By forcing the system to run an older, vulnerable firmware version, an attacker can exploit known vulnerabilities to decrypt protected memory, resulting in unauthorized information disclosure.

Description OSIDB Bzimport 2026-11-10 22:21:38 UTC 
Use of a per-part static key in the ASP Bootloader could allow an attacker to downgrade the Secure Encrypted Virtualization (SEV) firmware and exploit known vulnerabilities to decrypt memory potentially resulting in loss of confidentiality.
