# Alpine iLX-F511 Bluetooth stack reads past buffer, leaks memory

The libanwbtstack.so Bluetooth component on Alpine iLX-F511 car head units reads past the end of an allocated buffer in prh_rfcomm_cc_process_test when handling data from a paired device. An attacker who can pair a malicious Bluetooth device can disclose sensitive information, and could chain it with other flaws to run code as root.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Alpine iLX-F511 libanwbtstack.so prh_rfcomm_cc_process_test Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of Alpine iLX-F511 devices. 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 prh_rfcomm_cc_process_test function. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-29018.
