On removal,\ncc2520_remove() only flushes the work.  The devm-managed FIFOP IRQ\nremains active until after ->remove() returns and can queue the work\nagain after that flush, allowing it to run after the private data is\nreleased.\n\nDisable the work with disable_work_sync() instead of flushing it, so\nthe handler can no longer queue it once removal begins.  Destroy the\nbuffer mutex last, since the worker and the stop callback invoked\nthrough ieee802154_unregister_hw() both take it.\n\nFound by an in-house static analysis tool.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/56a9919d8494fb118eebf167bef0622528fbf2e7","tags":[]},{"url":"https://git.kernel.org/stable/c/890a80d516a1447db5c21bf92841a82914ea897d","tags":[]},{"url":"https://git.kernel.org/stable/c/c68fd52c73b676aee67020011e98fea125a978f4","tags":[]},{"url":"https://git.kernel.org/stable/c/ff5891b266a7fc6a062710836be84f1cc19338b5","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
