Summary

CVE-2021-37673 affects TensorFlow versions where `tf.raw_ops.MapStage` fails a `CHECK` when the `key` input is not a valid non-empty tensor. An attacker can trigger this to cause a denial of service, because the implementation in map_stage_op.cc does not validate that input.

Mitigation

Patched in GitHub commit d7de67733925de196ec8863a33445b73f9562d1d. The fix will be included in TensorFlow 2.6.0, and the commit will be cherry-picked to TensorFlow 2.5.1, 2.4.3 and 2.3.4.
