Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/meson: Se corrige la fuga de recuento de referencias en meson_encoder_hdmi_init. La referencia de of_find_device_by_node() se toma; debemos usar put_device() para liberarla cuando ya no sea necesaria. Se añade la falta de put_device() en la ruta de error para evitar la fuga de recuento de referencias.
