  "details": "In the Linux kernel, the following vulnerability has been resolved:  net: usb: kaweth: remove TX queue manipulation in kaweth_set_rx_mode  kaweth_set_rx_mode(), the ndo_set_rx_mode callback, calls netif_stop_queue() and netif_wake_queue(). These are TX queue flow control functions unrelated to RX multicast configuration.  The premature netif_wake_queue() can re-enable TX while tx_urb is still in-flight, leading to a double usb_submit_urb() on the same URB:  kaweth_start_xmit() {     netif_stop_queue();     usb_submit_urb(kaweth-\u003etx_urb); }  kaweth_set_rx_mode() {     netif_stop_queue();     netif_wake_queue();             // wakes TX queue before URB is done }  kaweth_start_xmit() {     netif_stop_queue();     usb_submit_urb(kaweth-\u003etx_urb); // URB submitted while active }  This triggers the WARN in usb_submit_urb():    \"URB submitted while active\"  This is a similar class of bug fixed in rtl8150 by  - commit 958baf5eaee3 (\"net: usb: Remove disruptive netif_wake_queue in rtl8150_set_multicast\").  Also kaweth_set_rx_mode() is already functionally broken, the real set_rx_mode action is performed by kaweth_async_set_rx_mode(), which in turn is not a no-op only at ndo_open() time.",
