## Overview

A flaw was found in the Linux kernel's MediaTek DRM (Direct Rendering Manager) driver. When binding non-master display devices, the driver fails to release a device reference acquired during initialization. A local user could exploit this condition during device initialization or reconfiguration, causing a resource leak that may lead to a Denial of Service (DoS) through resource exhaustion.
