Summary
wifi: cfg80211: Fix use after free for wext
Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: cfg80211: Fix use after free for wext

Key information in wext.connect is not reset on (re)connect and can hold data from a previous connection.

Reset key data to avoid that drivers or mac80211 incorrectly detect a WEP connection request and access the freed or already reused memory.

Additionally optimize cfg80211smeconnect() and avoid an useless schedule of conn_work.
