Summary
CVE-2021-41215 affects TensorFlow, an open source machine learning platform. In affected versions, the shape inference code for `DeserializeSparse` can trigger a null pointer dereference, because the function assumes the `serialize_sparse` tensor has positive rank with `3` as its last dimension.
Mitigation
The fix will be included in TensorFlow 2.7.0. The commit will also be cherrypicked to TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4.
