CVE-2022-23578 Information

Description

Tensorflow is an Open Source Machine Learning Framework. If a graph node is invalid TensorFlow can leak memory in the implementation of ImmutableExecutorState::Initialize. Here we set item->kernel to nullptr but it is a simple OpKernel pointer so the memory that was previously allocated to it would leak. 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.
