CVE-2023-31316

Firmware execution-flow hijack via corrupted restore state

Published May 15, 2026 · Updated May 15, 2026

Firmware state corruption in affected AMD products allows local users to redirect VCN firmware execution during power-state restoration. The AMD Secure Processor fails to preserve hardware-configuration integrity across power save and restore, so a write outside the Trusted Memory Range alters restored state used by Video Core Next firmware. Exploitation requires local low-privilege access, a high-complexity power-state condition, and the ability to write beyond the TMR; resulting control-flow changes affect confidentiality, integrity, and availability.
