This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Sony XAV-AX8500 devices. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability.\n\nThe specific flaw exists within the implementation of the Bluetooth L2CAP protocol. 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 elysian-bt-service process.

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar c\u00f3digo arbitrario en los dispositivos Sony XAV-AX8500 afectados. Para explotar esta vulnerabilidad, un atacante debe primero emparejar un dispositivo Bluetooth malicioso con el sistema objetivo. La falla espec\u00edfica se encuentra en la implementaci\u00f3n del protocolo Bluetooth L2CAP. El problema se debe a la falta de una validaci\u00f3n adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos a un b\u00fafer basado en mont\u00f3n.
