CVE-2026-68215

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: radio-si476x: Unregister v4l2_device on probe failure<br /> <br /> si476x_radio_probe() registers radio-&gt;v4l2dev before allocating the V4L2<br /> controls and before registering the video device. If any of those later<br /> steps fails, probe returns through the exit label after freeing only the<br /> control handler.<br /> <br /> A failed probe does not call si476x_radio_remove(), so the<br /> v4l2_device_unregister() there is not reached. This leaves the parent<br /> device reference taken by v4l2_device_register() behind on the error path.<br /> <br /> Unregister the V4L2 device in the probe error path after freeing the<br /> controls.
