CVE-2022-41880

TensorFlow is an open source platform for machine learning. When the `BaseCandidateSamplerOp` function receives a value

TensorFlow is an open source platform for machine learning. When the BaseCandidateSamplerOp function receives a value in true_classes larger than range_max, a heap oob read occurs. We have patched the issue in GitHub commit b389f5c944cadfdfe599b3f1e4026e036f30d2d4.

The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.
