CVE-2022-41908Public exploitNetwork attack vector

Process crash via malformed PyFunc token

Published Nov 18, 2022 · Updated Apr 22, 2025

Improper input validation in Google TensorFlow before 2.8.4, 2.9.0 through 2.9.2, and 2.10.0 allows attackers to crash the process. MakeArgTuple passes the unvalidated token to Py_BuildValue and invokes a fatal CHECK when malformed UTF-8 prevents creation of the Python tuple. Exploitation requires a host application to pass attacker-controlled token bytes to tf.raw_ops.PyFunc; the resulting abort interrupts that process without reported data disclosure or modification.
