Alpine iLX-507 CarPlay Stack-based Buffer Overflow Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Alpine iLX-507 devices. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the implementation of the Apple CarPlay protocol. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26318.
