CVE-2024-53119

Local service interruption via accept-queue memory leak

Published Dec 2, 2024 · Updated May 23, 2026

Memory leak in Linux kernel virtio/vsock allows local users to exhaust memory by racing connection receipt with socket destruction. After accept_queue is flushed but before SOCK_DONE is set, virtio_transport_recv_listen() can create a child socket that vsock_enqueue_accept() retains without later removal. The race requires local access to exercise virtio/vsock during listener teardown, and repeated wins can deplete kernel memory and interrupt service.
