It does not guarantee that the worker is currently executing a work item, as worker-&gt;current_pwq is populated only while process_one_work() is running the work function.</p> <p>is_chained_work() can be reached while queueing on a draining or destroying workqueue. If a kworker outside work-item execution reaches that path, current_wq_worker() returns a worker but worker-&gt;current_pwq is NULL, and the chained-work test can fault before it emits the intended warning.</p> <p>Guard the chained-work test with worker-&gt;current_pwq. A kworker without current_pwq is not executing work on the target workqueue, so the helper should return false and let the draining/destroying warning fire.</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>workqueue: Fix NULL current_pwq deref in chained work check</p> <p>current_wq_worker() only tells us that %current is a kworker.
