Process termination via rank-check failure
Published Sep 16, 2022 · Updated Apr 23, 2025
Denial of service in TensorFlow before 2.7.2 and in 2.8.0 or 2.9.0 allows remote attackers to interrupt processing via malformed ragged tensors. The RaggedTensorToVariant kernel previously accepted rt_nested_splits tensors with ranks other than one, triggering a CHECK failure instead of returning an input error. Remote exploitation requires an exposed TensorFlow application to process attacker-controlled tensors; the consequence is process termination and service interruption without reported data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=< 2.7.2
- Affected versionversion=>= 2.8.0, < 2.8.1
- Affected versionversion=>= 2.9.0, < 2.9.1
