Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: iwlwifi: read txq-&gt;read_ptr under lock<br /> <br /> If we read txq-&gt;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-&gt;read_ptr under lock.
