Overview

CVE-2025-38648 is a medium-severity vulnerability. It was published on August 22, 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:

spi: stm32: Check for cfg availability in stm32_spi_probe

The stm32_spi_probe function now includes a check to ensure that the

pointer returned by of_device_get_match_data is not NULL before

accessing its members. This resolves a warning where a potential NULL

pointer dereference could occur when accessing cfg->has_device_mode.

Before accessing the 'has_device_mode' member, we verify that 'cfg' is

not NULL. If 'cfg' is NULL, an error message is logged.

This change ensures that the driver does not attempt to access

configuration data if it is not available, thus preventing a potential

system crash due to a NULL pointer dereference.

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.
