CVE-2026-46214

CVE-2026-46214 relates to the Linux kernel vsock/virtio transport: a backlog count leak occurs when vsock_assign_transport() fails or switches transport, because sk_acceptq_added() is called before transport validation and not removed on error. This can cause sk_acceptq_is_full() to reject new co...
