In the Linux kernel, the following vulnerability has been resolved: wifi:
mac80211: fix race condition on enabling fast-xmit fast-xmit must only be
enabled after the sta has been uploaded to the driver, otherwise it could
end up passing the not-yet-uploaded sta via drv_tx calls to the driver,
leading to potential crashes because of uninitialized drv_priv data. Add a
missing sta->uploaded check and re-check fast xmit after inserting a sta.
