Bluetooth Classic LMP Handle Flaw Exploitation

The vulnerability affects the stability and reliability of the vehicle's infotainment system by allowing unauthenticated Bluetooth Classic traffic to interact with low-level protocol handling. Since the issue occurs at the LMP controller layer, malformed control messages can be processed before any pairing or authentication takes place. As a result, the infotainment unit may enter an unstable state, leading to crashes, denial-of-service conditions, or sudden reboots triggered by external, non-trusted Bluetooth devices. This behavior exposes the system to unauthenticated disruption through its Bluetooth Classic interface.
