When probing the usbnet device, executing usbnet_link_change(dev, 0, 0); put the kevent work in global workqueue. However, the kevent has not yet been scheduled when the usbnet device is unregistered. Therefore, executing free_netdev() results in the &#34;free active object (kevent)&#34; error reported here.</p> <p>2. Another factor is that when calling usbnet_disconnect()-&gt;unregister_netdev(), if the usbnet device is up, ndo_stop() is executed to cancel the kevent. However, because the device is not up, ndo_stop() is not executed.</p> <p>The solution to this problem is to cancel the kevent before executing free_netdev().</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>usbnet: Prevents free active kevent</p> <p>The root cause of this issue are: 1.
