Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the wifi: iwlwifi: read txq->read ptr under lock in the Linux kernel. If txq->read ptr is read without a lock, it can result in reading the same value twice, then obtaining the lock, and reclaiming from there to two different places, but crucially reclaiming the same entry twice, resulting in the WARN ONCE() a little later. The fix is to read txq->read ptr under lock.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
