On unbind, devres frees the interrupt, which only waits for\nthe handler itself, and then releases the hwmon device and fan_data,\nso a pending fan_alarm_notify() can run after those frees.\n\nReplace INIT_WORK() with devm_work_autocancel(), registered before\ndevm_request_irq().  The devres cleanup then frees the interrupt\nfirst, so no new work can be queued, and cancels the work while\nfan_data and the hwmon device are still alive.\n\nThis issue was found by an in-house static analysis tool.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/30755d3a5782cd704c8921cac8ee66dffe4383ea","https://git.kernel.org/stable/c/594c62eea7c82f526054496e9fa9b895122a8016","https://git.kernel.org/stable/c/6e67d9bdac810edacef78cbaeedd34445aa8ceb7","https://git.kernel.org/stable/c/9b12bd724db9db318e3a68be17693583dc29a066","https://git.kernel.org/stable/c/a2471ed17b0e6ff7bfb6b2ea8e6e5b04c309d293"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-97582","score":0.00205,"percentile":0.10437,"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).
