"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: chips-media: wave5: Fix kthread worker destruction in polling mode\n\nFix the cleanup order in polling mode (irq < 0) to prevent kernel warnings\nduring module removal. Cancel the hrtimer before destroying the kthread\nworker to ensure work queues are empty.\n\nIn polling mode, the driver uses hrtimer to periodically trigger\nwave5_vpu_timer_callback() which queues work via kthread_queue_work().\nThe kthread_destroy_worker() function validates that both work queues\nare empty with WARN_ON(!list_empty(&worker->work_list)) and\nWARN_ON(!list_empty(&worker->delayed_work_list)).\n\nThe original code called kthread_destroy_worker() before hrtimer_cancel(),\ncreating a race condition where the timer could fire during worker\ndestruction and queue new work, triggering the WARN_ON.\n\nThis causes the following warning on every module unload in polling mode:\n\n ------------[ cut here ]------------\n WARNING: CPU: 2 PID: 1034 at kernel/kthread.c:1430\n kthread_destroy_worker+0x84/0x98\n Modules linked in: wave5(-) rpmsg_ctrl rpmsg_char ...\n Call trace:\n kthread_destroy_worker+0x84/0x98\n wave5_vpu_remove+0xc8/0xe0 [wave5]\n platform_remove+0x30/0x58\n ...\n ---[ end trace 0000000000000000 ]---"
