## Overview

A flaw was found in the Linux kernel's MAX98363 audio codec driver. A local user could trigger this vulnerability during audio stream configuration because internal stream parameters are left uninitialized in memory. This issue allows uninitialized values to be processed by the sound subsystem, potentially causing system instability or a Denial of Service (DoS).
