## Overview

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) subsystem. When handling local connections, the system miscalculates the required communication paths, allocating internal work queues that are not properly freed during connection teardown. A local user can exploit this vulnerability by repeatedly opening and closing local connections, triggering a kernel memory leak that can lead to resource exhaustion and a Denial of Service (DoS).
