## Overview

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.
