Overview

CVE-2025-38526 is a high-severity vulnerability. It was published on August 16, 2025 and has a CVSS 3.1 base score of 7.5 (HIGH).

Technical description

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

ice: add NULL check in eswitch lag check

The function ice_lag_is_switchdev_running() is being called from outside of

the LAG event handler code. This results in the lag->upper_netdev being

NULL sometimes. To avoid a NULL-pointer dereference, there needs to be a

check before it is dereferenced.

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.
