Summary

Null pointer dereference in `UncompressElement` in TensorFlow

Details

TensorFlow is an end-to-end open source platform for machine learning. The code for tf.raw_ops.UncompressElement can be made to trigger a null pointer dereference. The implementation obtains a pointer to a CompressedElement from a Variant tensor and then proceeds to dereference it for decompressing. There is no check that the Variant tensor contained a CompressedElement, so the pointer is actually nullptr. We have patched the issue in GitHub commit 7bdf50bb4f5c54a4997c379092888546c97c3ebd. 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.
