CVE-2022-29211Public exploit

CPU crash via unchecked NaN-to-integer conversion

Published May 20, 2022 · Updated Apr 22, 2025

Improper input validation in Google TensorFlow before 2.6.4 allows local users to crash CPU workloads with NaN histogram values. The CPU HistogramFixedWidthFunctor divides each supplied value to derive a bin index, then casts an unchecked NaN result to int32. Reachability requires local code to invoke the API on the CPU implementation; affected later branches can terminate the hosting process without disclosing or changing data.
