Reference binding to nullptr in RaggedTensorToVariant
Impact
An attacker can cause undefined behavior via binding a reference to null pointer in tf.raw_ops.RaggedTensorToVariant:
The implementation has an incomplete validation of the splits values, missing the case when the argument would be empty.
Patches
We have patched the issue in GitHub commit be7a4de6adfbd303ce08be4332554dff70362612.
The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.
