## Overview

A flaw was found in the Linux kernel's interconnect subsystem. When a dynamic memory allocation fails during path initialization, an object is prematurely freed while still being referenced in internal lists. This creates dangling pointers, which can be later accessed or modified. This use-after-free vulnerability can lead to system instability or a denial of service.
