"value": "In the Linux kernel, the following vulnerability has been resolved:\n\npds_core: fix use-after-free on workqueue during remove\n\nIn pdsc_remove(), the workqueue is destroyed before pdsc_teardown()\nis called. This ordering allows two paths to queue work on the\ndestroyed workqueue:\n\n1. If pdsc_teardown() -> pdsc_devcmd_reset() times out, the error\n path in pdsc_devcmd_locked() queues health_work.\n\n2. A NotifyQ event can trigger the ISR and queue work before free_irq()\n is called in pdsc_teardown().\n\nFix by moving destroy_workqueue() after pdsc_teardown() so the\nworkqueue outlives every queuer; destroy_workqueue() then flushes any\nwork still pending.\n\nDraining the queued work also requires ordering the teardown so the\nresources that work touches are freed last:\n\n - In pdsc_qcq_free(), after freeing the interrupt, cancel_work_sync()\n the queue's work and only then clear qcq->intx, so\n pdsc_process_adminq()'s read of qcq->intx for interrupt-credit\n return cannot race with the clear.\n\n - Free adminqcq before notifyqcq: the shared adminq ISR is released\n when adminqcq is freed, and the adminq work accesses notifyqcq, so\n both must be stopped before notifyqcq is freed."
