CVE-2021-47225

A vulnerability was found in the Linux kernel's mac80211 module, where closing an active AP interface while its associated APVLAN interfaces are still up can lead to a deadlock. This situation occurs because the system tries to lock a resource that is already held, causing the operation to freeze...
