In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: cfg80211: clear wdev-&gt;cqm_config pointer on free<br /> <br /> When we free wdev-&gt;cqm_config when unregistering, we also<br /> need to clear out the pointer since the same wdev/netdev<br /> may get re-registered in another network namespace, then<br /> destroyed later, running this code again, which results in<br /> a double-free.
