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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97600","source_modified_at":"2026-10-21T12:53:24.716Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"0da6bc8cc3417a5e452efb886ff2c61e72b743d6","lessThan":"4a1ba62a486a4c43af91d01661a95e82dc4aaefa","status":"affected","versionType":"git"},{"version":"0da6bc8cc3417a5e452efb886ff2c61e72b743d6","lessThan":"56a9919d8494fb118eebf167bef0622528fbf2e7","status":"affected","versionType":"git"},{"version":"0da6bc8cc3417a5e452efb886ff2c61e72b743d6","lessThan":"c68fd52c73b676aee67020011e98fea125a978f4","status":"affected","versionType":"git"},{"version":"0da6bc8cc3417a5e452efb886ff2c61e72b743d6","lessThan":"890a80d516a1447db5c21bf92841a82914ea897d","status":"affected","versionType":"git"},{"version":"0da6bc8cc3417a5e452efb886ff2c61e72b743d6","lessThan":"ff5891b266a7fc6a062710836be84f1cc19338b5","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97600","source_modified_at":"2026-10-21T12:53:24.716Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"3.17","status":"affected"},{"version":"0","lessThan":"3.17","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97600","source_modified_at":"2026-10-21T12:53:24.716Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"4a1ba62a486a4c43af91d01661a95e82dc4aaefa","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97600","source_modified_at":"2026-10-21T12:53:24.716Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"56a9919d8494fb118eebf167bef0622528fbf2e7","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97600","source_modified_at":"2026-10-21T12:53:24.716Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"890a80d516a1447db5c21bf92841a82914ea897d","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.002,"percentile":0.09308,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:22:14.197Z","modified_at":"2026-10-21T12:53:24.716Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97600","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:53:24.716Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97600","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/4a1ba62a486a4c43af91d01661a95e82dc4aaefa"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/56a9919d8494fb118eebf167bef0622528fbf2e7"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c68fd52c73b676aee67020011e98fea125a978f4"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/890a80d516a1447db5c21bf92841a82914ea897d"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ff5891b266a7fc6a062710836be84f1cc19338b5"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T12:53:24.716Z","content_hash":"1ccce34db1e8b3e8eefae540b1a1347a2866f79734dd122986d0ab72ef42c43c"}}
