Descriptions

A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of this because it occurs on a code path where a successful allocation has already occurred

** 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.

A flaw was found in the Linux kernel. The Wireless configuration API functionality mishandles resource cleanup in nl80211_get_ftm_responder_stats function. An attacker able to trigger the resource cleanup code path could use this flaw to crash the system. The highest threat from this vulnerability is to system availability.
