If a second call occurs while the URB is still active (e.g. during rapid firmware loading), usb_submit_urb() detects the active state and triggers a warning: &#39;URB submitted while active&#39;.</p> <p>Fix this by enforcing serialization: call usb_kill_urb() before submitting the new request. This ensures the URB is idle and safe to reuse.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>wifi: libertas: fix WARNING in usb_tx_block</p> <p>The function usb_tx_block() submits cardp-&gt;tx_urb without ensuring that any previous transmission on this URB has completed.
