Denial of service via unchecked shape allocation
Published Nov 18, 2022 · Updated Apr 22, 2025
Denial-of-service flaw in ndarray_tensor_bridge in Google TensorFlow before 2.8.4, 2.9.0 through 2.9.2, and 2.10.0 allows remote authenticated users to crash a service via crafted NumPy shapes. The bridge passes zero-length and oversized shape dimensions to NumPy allocation without checking for a null return, then dereferences the invalid result and segfaults. Exploitation requires an exposed TensorFlow-consuming service to process attacker-controlled shapes and user interaction; impact is a process or service interruption, with no confidentiality or integrity effect reported.

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=>= 2.10.0, < 2.10.1
- Affected versionversion=< 2.8.4
- Affected versionversion=>= 2.9.0, < 2.9.3
