{"schema":"threatline.record/2","record":{"id":"CVE-2026-98656","aliases":[],"summary":"iio: trigger: cancel reenable_work before freeing trigger","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: trigger: cancel reenable_work before freeing trigger\n\niio_trigger_notify_done_atomic() defers ->reenable() into\ntrig->reenable_work on the system workqueue, and the worker dereferences\nthe owning trigger through container_of().  Nothing cancels this work\nbefore iio_trig_release() frees the trigger, so a worker armed by the\nlast in-flight IRQ can outlive the free and touch freed memory.\n\nCancel it at the top of iio_trig_release(), which every free path\nreaches through the device core's final put_device().\n\nFound by an in-house static analysis tool.","categories":["Operating
