Mô tả CVE
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.
