Vulnerability in Linux

CVE-2026-98662

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