How to fix?

Upgrade AlmaLinux:9 kernel-rt to version 0:5.14.0-427.31.1.el9_4 or higher.
This issue was patched in ALSA-2024:5363.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt package and not the kernel-rt package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: read txq->read_ptr under lock

If we read txq->read_ptr without lock, we can read the same value twice, then obtain the lock, and reclaim from there to two different places, but crucially reclaim the same entry twice, resulting in the WARN_ONCE() a little later. Fix that by reading txq->read_ptr under lock.
