Descriptions

bluetoothd from bluez incorrectly saves adapters' Discoverable status when a device is powered down, and restores it when powered up. If a device is powered down while discoverable, it will be discoverable when powered on again. This could lead to inadvertent exposure of the bluetooth stack to physically nearby attackers.

bluetoothd de bluez guarda incorrectamente el estado Discoverable de los adaptadores cuando es apagado un dispositivo, y lo restaura cuando es encendido. Si un dispositivo es apagado mientras es detectado, será detectado cuando es encendido de nuevo. Esto podría conllevar a una exposición inadvertida de la pila bluetooth a atacantes físicamente cercanos
