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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0ff795163f37109a134b5a421558530f8d091544","tags":[]},{"url":"https://git.kernel.org/stable/c/19c3da6621a253f1f8b937ed91bc22330a930d9c","tags":[]},{"url":"https://git.kernel.org/stable/c/6611f78ec3fd4b33a00bfda20725b254a22979f6","tags":[]},{"url":"https://git.kernel.org/stable/c/90af7fde083e1b22c349c3a8b1626728e44e474c","tags":[]},{"url":"https://git.kernel.org/stable/c/9a2e7cdc0880e735aff0968ee402f2c92a992b9b","tags":[]},{"url":"https://git.kernel.org/stable/c/f222bb8c30cf5699c560b29179ff2bddcac1f950","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
