Remote Memory Exhaustion Vulnerability in Eclipse Milo by Eclipse
CVE-2026-63252
8.7HIGH
What is CVE-2026-63252?
In certain versions of Eclipse Milo, a vulnerability exists where UASC server transport handlers do not effectively release retained partial message chunks during channel disconnections. This oversight allows a remote unauthenticated client to repeatedly send partial messages, resulting in the exhaustion of pooled direct memory. Such behavior can potentially lead to server instability and unexpected termination, posing significant risks to continuous operation.
