Overview

CVE-2025-37860 is a medium-severity vulnerability. It was published on April 18, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

sfc: fix NULL dereferences in ef100_process_design_param()

Since cited commit, ef100_probe_main() and hence also

ef100_check_design_params() run before efx->net_dev is created;

consequently, we cannot netif_set_tso_max_size() or _segs() at this

point.

Move those netif calls to ef100_probe_netdev(), and also replace

netif_err within the design params code with pci_err.

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.
