CVE-2022-23589 Information

Description

Tensorflow is an Open Source Machine Learning Framework. Under certain scenarios Grappler component of TensorFlow can trigger a null pointer dereference. There are 2 places where this can occur for the same malicious alteration of a SavedModel file (fixing the first one would trigger the same dereference in the second place). First during constant folding the GraphDef might not have the required nodes for the binary operation. If a node is missing the correposning mul_child would be null and the dereference in the subsequent line would be incorrect. We have a similar issue during IsIdentityConsumingSwitch. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1 TensorFlow 2.6.3 and TensorFlow 2.5.3 as these are also affected and still in supported range.
