CVE-2026-43255

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