## Overview

A flaw was found in the Linux kernel, specifically within the `vsock/virtio` component. An incorrect order of flushing work items during the removal of a `virtio_vsock` object can lead to a use-after-free condition. This vulnerability allows a race condition where memory can be freed while still in use, potentially resulting in memory corruption and system instability or a denial of service.
