Description

In the Linux kernel, the following vulnerability has been resolved: iio: trigger: cancel reenable_work before freeing trigger iio_trigger_notify_done_atomic() defers ->reenable() into trig->reenable_work on the system workqueue, and the worker dereferences the owning trigger through container_of(). Nothing cancels this work before iio_trig_release() frees the trigger, so a worker armed by the last in-flight IRQ can outlive the free and touch freed memory. Cancel it at the top of iio_trig_release(), which every free path reaches through the device core's final put_device(). Found by an in-house static analysis tool.
