Subject: Re: [PATCH] workqueue: Fix NULL current_pwq deref in flush dependency check
Date: Sat, 26 Sep 2026 22:30:46 -1000 [thread overview]
Message-ID: <42a21c8fdeb903d8511a279b5cf2e242@kernel.org> (raw)
In-Reply-To: <20260925-wq_flush_dep_fix-v1-1-fc5a9de31828@oss.qualcomm.com>
Applied to wq/for-7.3-fixes.
- is_chained_work() has the same problem. It dereferences
worker->current_pwq after checking only worker. It is only reached when
queueing on a draining or destroying workqueue, but a kworker outside a
work item would crash there the same way. Can you send a fix for that
one too?
Thanks.
