CVE-2022-23578
If a graph node is invalid, TensorFlow can leak memory in the implementation of `ImmutableExecutorState::Initialize`.
Does this matter?
Lower severity and a low EPSS score (0.72%). Track it; it rarely justifies an emergency change on its own.
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.
