- Summary
- cfg80211: fix race in netlink owner interface destruction
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
cfg80211: fix race in netlink owner interface destruction
My previous fix here to fix the deadlock left a race where the exact same deadlock (see the original commit referenced below) can still happen if cfg80211_destroy_ifaces() already runs while nl80211_netlink_notify() is still marking some interfaces as nl_owner_dead.
The race happens because we have two loops here - first we dev_close() all the netdevs, and then we destroy them. If we also have two netdevs (first one need only be a wdev though) then we can find one during the first iteration, close it, and go to the second iteration -- but then find two, and try to destroy also the one we didn't close yet.
Fix this by only iterating once.
