Descripcion

The TrustZone implementation in certain Broadcom MediaxChange firmware could allow an unauthenticated, physically proximate attacker to achieve arbitrary code execution in the TrustZone Trusted Execution Environment (TEE) of an affected device.

Exploitation is possible only when the attacker can disassemble the device in order to control the voltage/current for chip pins.
