Ubuntu.comUB:CVE-2024-36922CVE-2024-36922
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.
