"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntty: serial: max3100: shut down timer before freeing port\n\nmax3100_shutdown() stops the polling timer but returns early during\nsystem suspend. If the SPI device is unbound before resume, the serial\ncore does not call max3100_shutdown() again, so max3100_remove() frees\nthe port while the timer remains armed. max3100_timeout() may then\naccess the freed port and re-arm the timer.\n\nAdd final timer teardown to max3100_remove() and use\ntimer_shutdown_sync() to prevent a racing callback from re-arming it.\nAlso free the IRQ and destroy the workqueue there before freeing the\nport. Keep timer_delete_sync() in max3100_shutdown() so that a\nsubsequent open() can re-arm the timer.\n\nThe workqueue is created before request_irq() and destroyed on both\nrequest_irq() failure and normal shutdown. Its presence at remove thus\nidentifies the IRQ left registered when suspend bypasses shutdown.\n\nFree the IRQ before destroying the workqueue, in both\nmax3100_shutdown() and max3100_remove(), and cancel the pending work\nin between. free_irq() waits for a running interrupt handler to\nfinish and no new handler can start afterwards, so a racing handler\ncannot queue work on a workqueue that is being destroyed; the\nforce_end_work check in max3100_dowork() only narrows that window, as\na handler delayed between the check and queue_work() could still run\nafter the teardown has cleared the workqueue pointer. Cancelling the\nwork also keeps destroy_workqueue() from waiting on a queued work item\nin case remove() ever runs while the freezable workqueue is still\nfrozen, e.g. device removal during the resume window, before\nworkqueues are thawed.\n\nThis issue was found by an in-house static analysis tool."
