Local privilege escalation via unlocked TPM runtime state
Published Dec 12, 2025 · Updated Dec 12, 2025
Privilege escalation in American Megatrends International Aptio V before 5.041 allows local users to alter protected BIOS state. AMI identifies the locus only as TCG2 TPM runtime locking and has not disclosed which runtime object remains unlocked or how permissions are mishandled. Exploitation requires local low-privileged access; the exact integrity change and form of availability interruption are undisclosed.
