The security state of the calling processor into Trusted Firmware (TF-A) is not used and could potentially allow non-secure processors access to secure memories, access to crypto operations, and the ability to turn on and off subsystems within the SOC.

The Secure Flag passed to Versal™ Adaptive SoC’s Trusted Firmware for Cortex®-A processors (TF-A) for Arm’s Power State Coordination Interface (PSCI) commands were incorrectly set to secure instead of using the processor’s actual security state. This would allow the PSCI requests to appear they were from processors in the secure state instead of the non-secure state.
