Summary

CVE-2022-21741 affects TensorFlow, an open source machine learning framework. An attacker can craft a TFLite model that triggers a division by zero in the implementation of depthwise convolutions, because the convolution parameters, which are user controlled, feed a division that determines padding size without a check that the divisor is strictly positive.

Mitigation

The fix will be included in TensorFlow 2.8.0. The commit will also be cherrypicked to TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3.
