CVE-2019-19055

Estado: ModificadaMedia (5.5)—

** EN DISPUTA ** Una pérdida de memoria en la función nl80211_get_ftm_responder_stats() en el archivo net/wireless/nl80211.c en el kernel de Linux versiones hasta la versión 5.3.11, permite a atacantes causar una denegación de servicio (consumo de memoria) al desencadenar fallos de la función nl80211hdr_put(), también se conoce como CID-1399c59fa929. NOTA: terceros cuestionan la relevancia de esto porque se produce en una ruta de acceso de código donde ya se ha producido una asignación correcta.
