"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nworkqueue: Fix NULL current_pwq deref in chained work check\n\ncurrent_wq_worker() only tells us that %current is a kworker. It does\nnot guarantee that the worker is currently executing a work item, as\nworker->current_pwq is populated only while process_one_work() is running\nthe work function.\n\nis_chained_work() can be reached while queueing on a draining or\ndestroying workqueue. If a kworker outside work-item execution reaches\nthat path, current_wq_worker() returns a worker but worker->current_pwq is\nNULL, and the chained-work test can fault before it emits the intended\nwarning.\n\nGuard the chained-work test with worker->current_pwq. A kworker without\ncurrent_pwq is not executing work on the target workqueue, so the helper\nshould return false and let the draining/destroying warning fire."
