  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: light: gp2ap020a00f: drain irq_work after free_irq\n\nThe threaded IRQ handler queues data->work through irq_work_queue() so\nthe trigger is polled from a per-CPU context.  free_irq() does not flush\nan irq_work the handler already queued, so after gp2ap020a00f_remove()\nreturns that work may still run and call iio_trigger_poll() on data->trig,\nwhich the devm cleanup has already freed, causing a use-after-free.\n\nAdd irq_work_sync(&data->work) after free_irq() in remove() and in the\nprobe error path, mirroring commit 78601726d4a5 (\"iio: trigger: sysfs:\nfix use-after-free on remove\").\n\nFound by an in-house static analysis tool, confirmed by manual review.",
