CVE-2022-29207 Information

Description

TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0 2.8.1 2.7.2 and 2.6.4 multiple TensorFlow operations misbehave in eager mode when the resource handle provided to them is invalid. In graph mode it would have been impossible to perform these API calls but migration to TF 2.x eager mode opened up this vulnerability. If the resource handle is empty then a reference is bound to a null pointer inside TensorFlow codebase (various codepaths). This is undefined behavior. Versions 2.9.0 2.8.1 2.7.2 and 2.6.4 contain a patch for this issue.
