Описание
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.
A vulnerability was found in the mac80211 driver in the Linux kernel. This issue could lead to potential crashes or memory corruption due to of a situation where the driver attempts to utilize data structures that haven't been fully initialized yet.
