Overview

CVE-2025-37748 is a medium-severity vulnerability. It was published on May 1, 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:

iommu/mediatek: Fix NULL pointer deference in mtk_iommu_device_group

Currently, mtk_iommu calls during probe iommu_device_register before

the hw_list from driver data is initialized. Since iommu probing issue

fix, it leads to NULL pointer dereference in mtk_iommu_device_group when

hw_list is accessed with list_first_entry (not null safe).

So, change the call order to ensure iommu_device_register is called

after the driver data are initialized.

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.
