In the Linux kernel, the following vulnerability has been resolved:

hwmon: (gpio-fan) Fix use-after-free in alarm work

fan_alarm_irq_handler() queues fan_data->alarm_work, but nothing cancels it. fan_alarm_notify() dereferences fan_data and its hwmon device. On unbind, devres frees the interrupt, which only waits for the handler itself, and then releases the hwmon device and fan_data, so a pending fan_alarm_notify() can run after those frees.

Replace INIT_WORK() with devm_work_autocancel(), registered before devm_request_irq(). The devres cleanup then frees the interrupt first, so no new work can be queued, and cancels the work while fan_data and the hwmon device are still alive.

This issue was found by an in-house static analysis tool.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
