## Overview

A flaw was found in the Linux kernel's Intelligent Platform Management Interface (IPMI) message handler. When an error occurs during the startup of an IPMI interface, scheduled work may not be properly canceled. This can prevent the interface from being freed cleanly, potentially leading to resource exhaustion or system instability.
