CVE-2022-41899: `CHECK` fail via inputs in `SdcaOptimizer`
TensorFlow is an open source platform for machine learning. Inputs dense_features
or example_state_data
not of rank 2 will trigger a CHECK
fail in SdcaOptimizer
. We have patched the issue in GitHub commit 80ff197d03db2a70c6a111f97dcdacad1b0babfa. 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.
Inputs dense_features or example_state_data not of rank 2 will trigger a CHECK fail in SdcaOptimizer.
