Sources and claim methodology

Upstream source description

Bendix EC80 Brake ECU is vulnerable to a stack-based buffer overflow, which may allow an attacker to crash the ECU. A crafted payload can then be used to remotely execute arbitrary code or inject arbitrary CAN bus traffic. This could cause the loss of the ABS function, steering assist, speedometer, and shifting.
