Summary
CVE-2021-37676 affects TensorFlow versions in which an attacker can trigger undefined behavior by binding a reference to a null pointer in tf.raw_ops.SparseFillEmptyRows. The shape inference implementation does not check that input arguments are not empty tensors.
Mitigation
Patched in GitHub commit 578e634b4f1c1c684d4b4294f9e5281b2133b3ed. The fix will be included in TensorFlow 2.6.0 and cherrypicked to TensorFlow 2.5.1, 2.4.3, and 2.3.4.
