Summary

CVE-2022-29197 affects TensorFlow before versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4. The implementation of `tf.raw_ops.UnsortedSegmentJoin` does not fully validate its input arguments, and it assumes `num_segments` is a scalar without checking it before reading its value. This produces a `CHECK`-failure that can be used to trigger a denial of service.

Mitigation

Fixed in TensorFlow versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, which contain a patch for this issue.
