Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: iwlwifi: read txq->read_ptr under lock<br />
<br />
If we read txq->read_ptr without lock, we can read the same<br />
value twice, then obtain the lock, and reclaim from there<br />
to two different places, but crucially reclaim the same<br />
entry twice, resulting in the WARN_ONCE() a little later.<br />
Fix that by reading txq->read_ptr under lock.
