Overview

CVE-2025-38127 is a high-severity vulnerability. It was published on July 3, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

ice: fix Tx scheduler error handling in XDP callback

When the XDP program is loaded, the XDP callback adds new Tx queues.

This means that the callback must update the Tx scheduler with the new

queue number. In the event of a Tx scheduler failure, the XDP callback

should also fail and roll back any changes previously made for XDP

preparation.

The previous implementation had a bug that not all changes made by the

XDP callback were rolled back. This caused the crash with the following

call trace:

[ +9.549584] ice 0000:ca:00.0: Failed VSI LAN queue config for XDP, error: -5

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
