ZDI-26-826: (0Day) (Pwn2Own) 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 prhrfcommccprocesstest 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.
