En el kernel de Linux se ha resuelto la siguiente vulnerabilidad:

gpio: arizona: Corrección de una fuga de PM en tiempo de ejecución en arizona_gpio_direction_out()

Al cambiar una línea GPIO persistente de entrada a salida se adquiere una referencia de PM en tiempo de ejecución sobre el dispositivo padre, pero si la posterior llamada a regmap_update_bits() falla, la referencia nunca se libera y ningún direction_in() posterior puede equilibrarla, ya que la dirección nunca llegó a cambiar. Se libera la referencia en la ruta de fallo de la actualización.
