Overview

CVE-2025-38167 is a medium-severity vulnerability. It was published on July 3, 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:

fs/ntfs3: handle hdr_first_de() return value

The hdr_first_de() function returns a pointer to a struct NTFS_DE. This

pointer may be NULL. To handle the NULL error effectively, it is important

to implement an error handler. This will help manage potential errors

consistently.

Additionally, error handling for the return value already exists at other

points where this function is called.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
