Overview

CVE-2025-38275 is a medium-severity vulnerability. It was published on July 10, 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:

phy: qcom-qmp-usb: Fix an NULL vs IS_ERR() bug

The qmp_usb_iomap() helper function currently returns the raw result of

devm_ioremap() for non-exclusive mappings. Since devm_ioremap() may return

a NULL pointer and the caller only checks error pointers with IS_ERR(),

NULL could bypass the check and lead to an invalid dereference.

Fix the issue by checking if devm_ioremap() returns NULL. When it does,

qmp_usb_iomap() now returns an error pointer via IOMEM_ERR_PTR(-ENOMEM),

ensuring safe and consistent error handling.

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.
