CVE-2026-18281

Sony XAV-9500ES l2_reassemble_sdu 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 Bluetooth L2CAP 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-29072.

Summary		(es) Vulnerabilidad de ejecución remota de código por desbordamiento de búfer basado en montículo l2_reassemble_sdu en Sony XAV-9500ES. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de dispositivos Sony XAV-9500ES. Un atacante debe primero obtener la capacidad de emparejar un dispositivo Bluetooth malicioso con el sistema objetivo para explotar esta vulnerabilidad. La falla específica existe en el manejo de paquetes Bluetooth L2CAP. El problema resulta de la falta de validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos a un búfer basado en montículo. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del dispositivo. Fue ZDI-CAN-29072.
