Description
A flaw was found in the Linux kernel's kaweth USB network driver. The kaweth_set_rx_mode() function incorrectly manipulates the transmit (TX) queue, allowing it to be re-enabled while a USB Request Block (URB) is still active. This can result in the same URB being submitted twice, leading to a kernel warning and potentially causing system instability or a denial of service (DoS).
