CVE-2025-38039 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Avoid WARN_ON when configuring MQPRIO with HTB offload enabled When attempting to enable MQPRIO while HTB offload is already configured, the driver currently returns `-EINVAL` and triggers a `WARN_ON`, leading to an unnecessary call trace. Update the code to handle this case more gracefully by returning `-EOPNOTSUPP` instead, while also providing a helpful user message.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
