Overview

CVE-2025-37862 is a medium-severity vulnerability. It was published on May 9, 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:

HID: pidff: Fix null pointer dereference in pidff_find_fields

This function triggered a null pointer dereference if used to search for

a report that isn't implemented on the device. This happened both for

optional and required reports alike.

The same logic was applied to pidff_find_special_field and although

pidff_init_fields should return an error earlier if one of the required

reports is missing, future modifications could change this logic and

resurface this possible null pointer dereference again.

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.
