Original description
The description as published by the source.
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: Lock wiphy in cfg80211_get_station
Wiphy should be locked before calling rdev_get_station() (see lockdep
assert in ieee80211_get_station()).
This fixes the following kernel NULL dereference:
