CVE-2022-35984Network attack vector

Denial of service via int64 shape assertion

Published Sep 16, 2022 · Updated Apr 23, 2025

Reachable assertion in Google TensorFlow before 2.7.2 allows remote attackers to interrupt service via crafted int64 shape input. The ParameterizedTruncatedNormal kernel treats a valid int64 shape tensor as int32, causing a mismatched-type CHECK failure and process crash. Exploitation requires a TensorFlow execution path that accepts attacker-controlled shape data; impact is denial of service without reported data disclosure or modification.
