  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nhwmon: (gpio-fan) Fix use-after-free in alarm work\n\nfan_alarm_irq_handler() queues fan_data-\u003ealarm_work, but nothing\ncancels it.  fan_alarm_notify() dereferences fan_data and its hwmon\ndevice.  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.",
