The IIO core when done using this trigger will call `iio_trigger_put()` to drop the reference count by 1.</p> <p>Without the matching `iio_trigger_get()` in the driver the reference count can reach 0 too early, the trigger gets freed while still in use and a use-after-free occurs.</p> <p>Fix this by getting a reference to the trigger before assigning it to the IIO device.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>iio: mma8452: Fix trigger reference couting</p> <p>The mma8452 driver directly assigns a trigger to the struct iio_dev.
