CVE-2022-35981Public exploitNetwork attack vector

Process crash via fatal gradient index check

Published Sep 16, 2022 · Updated Apr 23, 2025

Reachable assertion in Google TensorFlow before 2.7.2 and in 2.8.0 and 2.9.0 allows remote attackers to crash the process via malformed tensors. FractionalMaxPoolGrad uses a fatal CHECK to validate an input-backpropagation index derived from supplied pooling sequences instead of returning an InvalidArgument error. Exploitation requires an application to pass attacker-controlled, incorrectly sized tensors to the operation and terminates that TensorFlow process, with no reported data disclosure or modification.
