## Overview

A flaw was found in the Linux kernel's HID (Human Interface Device) roccat driver. When a roccat device is destroyed, the driver fails to properly free buffered reports, leading to a memory leak. A local attacker could potentially exploit this to exhaust system memory, resulting in a Denial of Service (DoS).
