## Technical details

Improper initialization in the motherboard's memory controller or related hardware component fails to enforce access restrictions, allowing an attacker with physical access to insert a device that can directly access system memory. The vulnerability requires physical proximity and device insertion capability; no authentication is bypassed as the issue exists at the hardware initialization level.
