CVE-2024-35789 Information

Description

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.
