Descriptions

In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes

When moving a station out of a VLAN and deleting the VLAN afterwards, the
fast_rx entry still holds a pointer to the VLAN's netdev, which can cause
use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx
after the VLAN change.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: mac80211: comprobar/borrar fast rx para cambios de VLAN que no sean 4addr sta Al mover una estación fuera de una VLAN y eliminar la VLAN después, la entrada fast_rx todavía contiene un puntero a netdev de la VLAN, lo que puede causar errores de uso después de la liberación. Solucione este problema llamando inmediatamente a ieee80211_check_fast_rx después del cambio de VLAN.
