CVE-2022-23593
MEDIUM5.9EPSS 0.31%Segfault in `simplifyBroadcast` in Tensorflow
發布日:2022/2/9修改日:2025/10/9
描述
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.
