Process crash via unchecked Requantize tensor ranks
Published Sep 16, 2022 · Updated Apr 23, 2025
Improper input validation in Google TensorFlow before 2.7.2, plus 2.8.0 and 2.9.0, allows remote attackers to crash a process. RequantizeOp::Compute reads the first float from four range tensors without first requiring scalar shapes, so a nonzero-rank argument triggers a segmentation fault. Reachability requires an application to pass attacker-controlled tensors to Requantize; the demonstrated consequence is process termination and resulting service interruption.

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
