Code execution via AVRCP heap overflow
Published Aug 20, 2026 · Updated Aug 20, 2026
Heap-based buffer overflow in AVRCP_Br_Response_Parser in Sony XAV-9500ES 3.02.00 allows attackers to execute code via crafted AVRCP packets. The parser copies length-controlled data from an AVRCP Bluetooth response into a heap buffer without validating that the supplied length fits the destination allocation. Reachability requires a malicious Bluetooth device to pair with the receiver first, limiting exposure to attackers within pairing range, but successful exploitation runs code in the device context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
