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.
