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tool.","score":null,"severity":"unknown","published":"2026-09-25T10:22:03.041Z","modified":"2026-10-30T12:37:29.592Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"d6fe1360f42e86262153927986dea6502daff703","status":"affected","lessThan":"7f96803f612134f585ab3b39e6d5b2d4b9c0606f","versionType":"git"},{"version":"d6fe1360f42e86262153927986dea6502daff703","status":"affected","lessThan":"594c62eea7c82f526054496e9fa9b895122a8016","versionType":"git"},{"version":"d6fe1360f42e86262153927986dea6502daff703","status":"affected","lessThan":"6e67d9bdac810edacef78cbaeedd34445aa8ceb7","versionType":"git"},{"version":"d6fe1360f42e86262153927986dea6502daff703","status":"affected","lessThan":"e9fc7d53b2eb34c0a607d1659f49b46911aaf16c","versionType":"git"},{"version":"d6fe1360f42e86262153927986dea6502daff703","status":"affected","lessThan":"9b12bd724db9db318e3a68be17693583dc29a066","versionType":"git"},{"version":"d6fe1360f42e86262153927986dea6502daff703","status":"affected","lessThan":"30755d3a5782cd704c8921cac8ee66dffe4383ea","versionType":"git"},{"version":"d6fe1360f42e86262153927986dea6502daff703","status":"affected","lessThan":"c6ab7f855891877a16d2e2ddf0cd0305fd098a85","versionType":"git"},{"version":"d6fe1360f42e86262153927986dea6502daff703","status":"affected","lessThan":"a2471ed17b0e6ff7bfb6b2ea8e6e5b04c309d293","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-97582"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"2.6.37","status":"affected"},{"version":"0","status":"unaffected","lessThan":"2.6.37","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.222","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.189","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.158","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.111","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.53","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.7","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-97582"}],"remediation":[],"references":["https://git.kernel.org/stable/c/7f96803f612134f585ab3b39e6d5b2d4b9c0606f","https://git.kernel.org/stable/c/594c62eea7c82f526054496e9fa9b895122a8016","https://git.kernel.org/stable/c/6e67d9bdac810edacef78cbaeedd34445aa8ceb7","https://git.kernel.org/stable/c/e9fc7d53b2eb34c0a607d1659f49b46911aaf16c","https://git.kernel.org/stable/c/9b12bd724db9db318e3a68be17693583dc29a066","https://git.kernel.org/stable/c/30755d3a5782cd704c8921cac8ee66dffe4383ea","https://git.kernel.org/stable/c/c6ab7f855891877a16d2e2ddf0cd0305fd098a85","https://git.kernel.org/stable/c/a2471ed17b0e6ff7bfb6b2ea8e6e5b04c309d293"],"sources":[{"name":"CVE","id":"CVE-2026-97582","modified":"2026-10-30T12:37:29.592Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-97582"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T14:00:21.365Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T00:00:32.242Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
