Overview

CVE-2025-38559 is a medium-severity vulnerability. It was published on August 19, 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:

platform/x86/intel/pmt: fix a crashlog NULL pointer access

Usage of the intel_pmt_read() for binary sysfs, requires a pcidev. The

current use of the endpoint value is only valid for telemetry endpoint

usage.

Without the ep, the crashlog usage causes the following NULL pointer

exception:

BUG: kernel NULL pointer dereference, address: 0000000000000000

Oops: Oops: 0000 [#1] SMP NOPTI

RIP: 0010:intel_pmt_read+0x3b/0x70 [pmt_class]

Augment struct intel_pmt_entry with a pointer to the pcidev to avoid

the NULL pointer exception.

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.
