In the Linux kernel, the following vulnerability has been resolved: nfc: pn533: properly drop the usb interface reference on disconnect When the device is disconnected from the driver, there is a "dangling" reference count on the usb interface that was grabbed in the probe callback. Fix this up by properly dropping the reference after we are done with it.
En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: nfc: pn533: soltar correctamente la referencia de la interfaz USB al desconectarse Cuando el dispositivo se desconecta del controlador, hay un contador de referencias 'colgante' en la interfaz USB que fue obtenida en la función de devolución de llamada de sondeo. Solucionar esto soltando correctamente la referencia después de que hayamos terminado con ella.
