Summary
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 with Control Interface access can specify an excessive message length, causing unbounded memory allocation that may abort the agent process, resulting in loss of orchestration services.
Risk Assessment
The risk includes agent crash, leading to disruption of orchestration services and potential unavailability of managed workloads.
Recommendation
It is recommended to update Eclipse Ankaios to a version above 1.0.1 that includes a fix for message length limiting.
Other vulnerabilities in Eclipse Ankaios
See all- CVE-2026-86836High
In Eclipse Ankaios versions 0.1.0 through 1.0.2, the agent creates workload files and Control Interface FIFOs under a predictable path derived from the agent name and a hash of the workload configuration. If the path already exists at agent startup, it is reused without validating owner or permissions, allowing a local user to impersonate the workload and modify cluster state.
- CVE-2026-84173High
In Eclipse Ankaios versions v0.5.1 through v1.0.1, the agent-side Control Interface authorizer incorrectly evaluates multi-segment allow rules whose first path segment is a wildcard. An authenticated workload with restricted access can submit a CompleteStateRequest or UpdateStateRequest with an empty field mask, which may be incorrectly authorized, allowing read of the complete cluster state or modification outside its authorized subtree.
Original NVD description (English source)
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.
