Overview

CVE-2025-38715 is a high-severity vulnerability. It was published on September 4, 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:

hfs: fix slab-out-of-bounds in hfs_bnode_read()

This patch introduces is_bnode_offset_valid() method that checks

the requested offset value. Also, it introduces

check_and_correct_requested_length() method that checks and

correct the requested length (if it is necessary). These methods

are used in hfs_bnode_read(), hfs_bnode_write(), hfs_bnode_clear(),

hfs_bnode_copy(), and hfs_bnode_move() with the goal to prevent

the access out of allocated memory and triggering the crash.

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.
