"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/dp_mst: garantizar que el puntero mst_primary sea v\u00e1lido en drm_dp_mst_handle_up_req() Al recibir un mensaje de solicitud de activaci\u00f3n de MST de un hilo en drm_dp_mst_handle_up_req(), la topolog\u00eda de MST podr\u00eda eliminarse de otro hilo mediante drm_dp_mst_topology_mgr_set_mst(false), liberando mst_primary y estableciendo drm_dp_mst_topology_mgr::mst_primary en NULL. Esto podr\u00eda conducir a una desreferencia/use after free de NULL de mst_primary en drm_dp_mst_handle_up_req(). Evite lo anterior manteniendo una referencia para mst_primary en drm_dp_mst_handle_up_req() mientras se usa. v2: Se soluciona el problema de liberar la solicitud si falla la obtenci\u00f3n de una referencia mst_primary."
