No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In Eclipse Milo versions 0.6.0 through 1.1.4, UASC server transport handlers fail to release retained partial message chunks when a channel disconnects, allowing a remote unauthenticated client to exhaust pooled direct memory by repeatedly sending incomplete chunks and disconnecting, potentially terminating the server.
