CVE-2025-48507Public exploit

Secure-resource access via omitted processor security state

Published Nov 23, 2025 · Updated Nov 23, 2025

Improper validation in AMD Trusted Firmware and PMU Firmware through 2025.1 allows local users to access secure SoC resources. Trusted Firmware omits the calling Cortex-A processor's secure or non-secure state when forwarding requests, so PMU Firmware authorizes operations without that boundary. Low-privileged local access and user participation are required; successful requests expose secure memory, cryptographic operations, and SoC subsystem controls.
