## Overview

A flaw was found in the Linux kernel's TPS6598x USB Type-C driver. When a partner device connects, the driver fails to properly initialize temporary memory structures allocated on the stack before registering the connection. An attacker connecting a USB Type-C device could exploit this flaw to trigger the execution of invalid memory pointers or leak internal stack data. This could result in a Denial of Service (DoS) via a system crash, arbitrary code execution, or information disclosure.
