Descriptions

A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to corrupt a linked list and, in turn, potentially execute code.

Un error de administración de listas en el manejo de BSS en la pila mac80211 en el kernel de Linux versiones 5.1 hasta 5.19.14, podría ser usado por atacantes locales (capaces de inyectar tramas WLAN) para corromper una lista enlazada y, a su vez, ejecutar potencialmente código

A list corruption flaw was found in cfg80211_add_nontrans_list in the net/wireless/scan.c function in the Linux kernel. This flaw could lead to a denial of service.
