CVE-2025-37862 Information

May 10, 2025 cve

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.
