Technical details
This vulnerability is a heap-based buffer overflow in the AVRCP_Br_Response_Parser component of the Sony XAV-9500ES. The root cause is insufficient validation of user-supplied data length before copying to a heap buffer, allowing an out-of-bounds write. The attack vector is network-adjacent (Bluetooth); an attacker must first obtain Bluetooth pairing capability with the target device—a precondition that requires physical proximity or social engineering. Successful exploitation allows remote code execution in the device context. Sony has issued a software update to address this vulnerability.
