Summary

CVE-2022-23579 affects TensorFlow's Grappler optimizer. An attacker can alter a `SavedModel` so that `SafeToRemoveIdentity` triggers `CHECK` failures, causing a denial of service.

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.
