  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmemstick: ms_block: destroy io_queue workqueue on removal\n\nmsb_init_disk() creates the per-card ordered workqueue msb-\u003eio_queue with\nalloc_ordered_workqueue(). It is torn down with destroy_workqueue() only\non the init error path; msb_remove() never destroys it. msb_stop() merely\nflushes the queue, and neither msb_data_clear() nor put_disk() free it. As\na result every card insert/remove cycle leaks the workqueue and its\nkworker, exhausting kernel memory over repeated cycles.\n\nDestroy the workqueue in msb_remove() after the disk has been removed and\nthe queue drained.",
