What is CVE-2026-85201?
CVE-2026-85201 is a medium-severity denial of service vulnerability in Eclipse Ankaios, published on 7 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
In Eclipse Ankaios versions 0.1.0 through 1.0.1, the agent does not limit the length declared by a workload in a length-delimited protobuf message received through the Control Interface FIFO. A workload granted Control Interface access can specify an excessive message length, causing an unbounded memory allocation that may abort the Ankaios agent process. This results in loss of orchestration services for workloads managed by the affected agent.
