"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: No hacer referencia a dc_sink en is_dsc_need_re_compute [Por qu\u00e9] Cuando se desconecta uno de los monitores conectados despu\u00e9s del concentrador mst, se produce una desreferencia de puntero nulo. Esto se debe a que dc_sink se libera inmediatamente en early_unregister() o detect_ctx(). Cuando se confirma un nuevo estado que hace referencia directa a la informaci\u00f3n almacenada en dc_sink, se producir\u00e1 una desreferencia de puntero nulo. [C\u00f3mo] Eliminar la condici\u00f3n de comprobaci\u00f3n redundante. La condici\u00f3n relevante ya deber\u00eda estar cubierta comprobando si dsc_aux es nulo o no. Tambi\u00e9n se restablece dsc_aux a NULL cuando se desconecta el conector."
