Summary

Unverified AXI Address in Subsystem Mode Commands Enables Denial of Service

Details

Missing authorization in Caliptra Core Runtime Firmware (INVOKEDPEMLDSA87, CMAESGCMDECRYPTDMA, EXTERNALMAILBOXCMD commands) in subsystem mode allows a privileged local attacker to cause a denial of service via mailbox commands containing unverified AXI addresses. The security impact beyond availability is integration-specific.

This issue affects Core Runtime Firmware: 2.1.0.
