      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/msm/dpu: mover la asignaci\u00f3n del conector de dpu_encoder a atomic_enable() Para los casos en los que se configur\u00f3 connectors_changed de crtc sin que se alternara enable/active, hay una llamada a atomic_enable() seguida de una atomic_disable() pero sin una atomic_mode_set(). Esto da como resultado un acceso ptr NULL para la llamada dpu_encoder_get_drm_fmt() en atomic_enable() ya que el conector de dpu_encoder se borr\u00f3 en atomic_disable() pero no se reasign\u00f3 ya que no hubo una llamada a atomic_mode_set(). Corrija el acceso ptr NULL moviendo la asignaci\u00f3n para atomic_enable() y tambi\u00e9n use drm_atomic_get_new_connector_for_encoder() para obtener el conector de atomic_state.
