Technical details
The vulnerability stems from an expected behavior violation in the CAN bus implementation of the Wireless Control Module (WCM). An attacker can use a CAN error-frame injection technique to target periodic WCM transmissions, driving the transmit error counter (TEC) past the bus-off threshold (255). Once in the 'bus-off' state, the WCM ceases all transmissions, including the immobilizer's shutdown command. Because peer Electronic Control Units (ECUs) do not treat the absence of WCM messages as a security exception, they continue normal operation, effectively bypassing the anti-theft mechanism. This requires adjacent network access to the vehicle's CAN bus.
