CVE-2022-23593 Information

Description

Tensorflow is an Open Source Machine Learning Framework. The simplifyBroadcast function in the MLIR-TFRT infrastructure in TensorFlow is vulnerable to a segfault (hence denial of service) if called with scalar shapes. If all shapes are scalar then maxRank is 0 so we build an empty SmallVector. The fix will be included in TensorFlow 2.8.0. This is the only affected version.
