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

wifi: cfg80211: init wiphy_work before allocating rfkill fails

syzbort reported a uninitialize wiphy_work_lock in cfg80211_dev_free. [1]

After rfkill allocation fails, the wiphy release process will be performed,
which will cause cfg80211_dev_free to access the uninitialized wiphy_work
related data.

Move the initialization of wiphy_work to before rfkill initialization to
avoid this issue.

[1]
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.
