UBUNTU-CVE-2025-40140: Low severity ubuntu/linux vulnerability

Q: Which systems are realistically exposed to this issue?

Systems using the affected Ubuntu kernel packages and an RTL8150 USB network adapter are the relevant exposure set. The vulnerable code is in the RTL8150 USB network driver.

Q: What conditions are needed to trigger the problem?

The transmit queue must be woken by the driver's receive-mode callback while a transmit USB request is still in flight, allowing rtl8150_start_xmit to submit the same transmit URB again. Exploitation requires local access and low privileges; no user interaction is required.

Q: What is the expected impact?

The reported condition is a warning caused by double submission of a USB URB during transmission. The supplied severity vector indicates low availability impact and no confidentiality or integrity impact.

Q: What change addresses the issue?

The fix removes netif_stop_queue and netif_wake_queue calls from rtl8150_set_multicast. Receive-mode synchronization is handled by the network core through dev_set_rx_mode.

Published Nov 12, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved: net: usb: Remove disruptive netifwakequeue in rtl8150setmulticast syzbot reported WARNING in rtl8150startxmit/usbsubmiturb. This is the sequence of events that leads to the warning: rtl8150startxmit() { netifstopqueue(); usbsubmiturb(dev->txurb); } rtl8150setmulticast() { netifstopqueue(); netifwakequeue(); <-- wakes up TX queue before URB is done } rtl8150startxmit() { netifstopqueue(); usbsubmiturb(dev->txurb); <-- double submission } rtl8150setmulticast being the ndosetrxmode callback should not be calling netifstopqueue and notifstartqueue as these handle TX queue synchronization. The net core function devsetrxmode handles the synchronization for rtl8150setmulticast making it safe to remove these locks.

Compensating control
Modify the Linux kernel rtl8150 driver so rtl8150_set_multicast does not call netif_stop_queue() or netif_wake_queue()/netif_start_queue(); rely on dev_set_rx_mode synchronization for TX queue handling.

Frequently Asked Questions

Which systems are realistically exposed to this issue?

Systems using the affected Ubuntu kernel packages and an RTL8150 USB network adapter are the relevant exposure set. The vulnerable code is in the RTL8150 USB network driver.

What conditions are needed to trigger the problem?

The transmit queue must be woken by the driver's receive-mode callback while a transmit USB request is still in flight, allowing rtl8150_start_xmit to submit the same transmit URB again. Exploitation requires local access and low privileges; no user interaction is required.

What is the expected impact?

The reported condition is a warning caused by double submission of a USB URB during transmission. The supplied severity vector indicates low availability impact and no confidentiality or integrity impact.

What change addresses the issue?

The fix removes netif_stop_queue and netif_wake_queue calls from rtl8150_set_multicast. Receive-mode synchronization is handled by the network core through dev_set_rx_mode.
