{"schema":"threatline.record/2","record":{"id":"CVE-2026-97582","aliases":[],"summary":"hwmon: (gpio-fan) Fix use-after-free in alarm work","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->alarm_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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
