Overview

CVE-2026-45874 is a medium-severity vulnerability. It was published on May 27, 2026 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:

phy: freescale: imx8qm-hsio: fix NULL pointer dereference

During the probe the refclk_pad pointer is set to NULL if the

'fsl,refclk-pad-mode' property is not defined in the devicetree node. But

in imx_hsio_configure_clk_pad() this pointer is unconditionally used which

could result in a NULL pointer dereference. So check the pointer before to

use it.

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.
