The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow when receiving fragmented HCI packets on a channel. An attacker can leverage this vulnerability to bypass the MTU check on a channel with enabled fragmentation. Consequently, this can lead to a buffer overflow in upper layer profiles, which can be used to obtain remote code execution.\nThe vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources."}, {"lang": "es", "value": "Existe una falla espec\u00edfica en la pila Bluetooth de la unidad MIB3. El problema se debe a la falta de una validaci\u00f3n adecuada de los datos proporcionados por el usuario, lo que puede provocar un desbordamiento de enteros al recibir paquetes HCI fragmentados en un canal. Un atacante puede aprovechar esta vulnerabilidad para eludir la comprobaci\u00f3n de MTU en un canal con la fragmentaci\u00f3n habilitada. En consecuencia, esto puede provocar un desbordamiento de b\u00fafer en los perfiles de capa superior, lo que puede utilizarse para obtener ejecuci\u00f3n remota de c\u00f3digo. La vulnerabilidad se descubri\u00f3 originalmente en el Skoda Superb III con unidad de infoentretenimiento MIB3 con n\u00famero de pieza OEM 3V0035820.
