CVE-2022-23593: Improper Check for Unusual or Exceptional Conditions
(updated )
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
.
