Summary

CVE-2021-37653 affects TensorFlow versions before the fix. An attacker can crash a process by triggering a floating point exception in `tf.raw_ops.ResourceGather`, which divides by `batch_size` without checking that it is not 0.

Mitigation

Fixed in GitHub commit ac117ee8a8ea57b73d34665cdf00ef3303bc0b11, included in TensorFlow 2.6.0. The commit is also cherry-picked to TensorFlow 2.5.1, 2.4.3 and 2.3.4.
