CWE-1193: Power-On of Untrusted Execution Core Before Enabling Fabric Access Control
The product enables components that contain untrusted firmware before memory and fabric access controls have been enabled.
Last updated
Overview
After initial reset, System-on-Chip (SoC) fabric access controls and other security features need to be programmed by trusted firmware as part of the boot sequence. If untrusted IPs or peripheral microcontrollers are enabled first, then the untrusted component can master transactions on the hardware bus and target memory or other assets to compromise the SoC boot firmware.
