CVE-2022-36014Network attack vector

Process crash via null-unsafe GraphDef attribute casts

Published Sep 16, 2022 · Updated Apr 23, 2025

Null pointer dereference in TensorFlow before 2.7.2, 2.8.0, and 2.9.0 allows remote attackers to crash GraphDef imports. GraphDefImporter::ArgNumType calls dyn_cast on a null value returned for a missing type-list, number, or type attribute instead of using a null-safe cast. A crafted GraphDef must reach the MLIR TensorFlow Graph importer; triggering the flaw terminates the importing process without reported data disclosure or modification.
