CVE-2022-23593
February 04, 2022
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.
