CVE-2022-29203Public exploit

Process crash via unchecked output-size multiplication

Published May 20, 2022 · Updated Apr 22, 2025

Integer overflow in Google TensorFlow before 2.6.4 and selected 2.7 through 2.9 releases allows local users to crash a process. SpaceToBatchND multiplies the input batch size by attacker-controlled block dimensions without overflow checking, then uses the wrapped result to allocate the output tensor. Reachability requires control of operation arguments; the bounded consequence is a CHECK assertion failure and process crash, not data access or modification.
