CVE-2026-85201: CWE-789 Memory allocation with excessive size value in Eclipse Foundation Eclipse Ankaios
Description
Eclipse Ankaios versions 0.1.0 through 1.0.1 contain a vulnerability where the agent does not limit the length declared by a workload in a length-delimited protobuf message received via the Control Interface FIFO. This allows a workload with Control Interface access to specify an excessively large message length, causing unbounded memory allocation and potentially aborting the agent process. This results in loss of orchestration services for workloads managed by the affected agent.

Technical Analysis
CVE-2026-85201 affects Eclipse Ankaios versions 0.1.0 through 1.0.1. The vulnerability arises because the agent does not enforce limits on the length field in a length-delimited protobuf message received through the Control Interface FIFO. A workload with Control Interface access can exploit this by specifying an excessively large message length, leading to unbounded memory allocation. This excessive allocation can cause the Ankaios agent process to abort, disrupting orchestration services for workloads managed by the agent.
Potential Impact
Successful exploitation results in the Ankaios agent process aborting due to unbounded memory allocation, causing loss of orchestration services for workloads managed by the affected agent. This can disrupt workload management but does not indicate direct code execution or privilege escalation based on the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided. Until a patch is available, restrict Control Interface access to trusted workloads only to reduce risk.
