Vulnerability Description
Tesla Model 3 bsa_server BIP Heap-based Buffer Overflow Arbitrary Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Tesla Model 3 vehicles. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability. The specific flaw exists within the bsa_server process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer.
