Summary

TensorFlow's implementation of `AvgPoolGrad` does not fully validate the input `orig_input_shape`. This causes a `CHECK` failure that can be used to trigger a denial of service attack.

Mitigation

Patched in GitHub commit 3a6ac52664c6c095aa2b114e742b0aa17fdce78f. The fix will be included in TensorFlow 2.10.0 and cherry-picked to TensorFlow 2.9.1, 2.8.1 and 2.7.2.
