CVE-2026-18282: (Pwn2Own) Sony XAV-9500ES AVRCP_Br_Response_Parser Heap-based Buffer Overflow Remote Code Execution Vulnerability
Sony XAV-9500ES AVRCPBrResponseParser Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Sony XAV-9500ES 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 handling of AVRCP packets. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-28995.

Frequently Asked Questions
Who can realistically exploit this issue?
An attacker must be network-adjacent to the device and able to pair a malicious Bluetooth device with the target system. No prior privileges are required, but user interaction is required according to the supplied vector.
What access does successful exploitation provide?
Successful exploitation can result in arbitrary code execution in the context of the affected Sony XAV-9500ES device. The reported impact includes compromise of confidentiality, integrity, and availability.
What attack traffic triggers the flaw?
The flaw is triggered through malformed AVRCP packets after pairing. It stems from insufficient validation of user-supplied data length before copying data into a heap-based buffer.
