Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: unlist vifs when their netdev is unregistered mac80211 only removes vifs from the local->interfaces list when an interface is removed via ieee80211_if_remove(), before it unregisters the netdev. However, it's possible for a netdev to be unregistered without going through that: When the netns that holds the wiphy is destroyed, the wiphy is supposed to move to the init_ns, but that can run into allocation failure
