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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/4a1ba62a486a4c43af91d01661a95e82dc4aaefa","https://git.kernel.org/stable/c/56a9919d8494fb118eebf167bef0622528fbf2e7","https://git.kernel.org/stable/c/890a80d516a1447db5c21bf92841a82914ea897d","https://git.kernel.org/stable/c/c68fd52c73b676aee67020011e98fea125a978f4","https://git.kernel.org/stable/c/ff5891b266a7fc6a062710836be84f1cc19338b5"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-97600","score":0.00201,"percentile":0.09854,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
