CVE-2022-36012

Assertion fail on MLIR empty edge names in TensorFlow

5.9 MediumFix available

TensorFlow is an open source platform for machine learning. When mlir::tfg::ConvertGenericFunctionToFunctionDef is given empty function attributes, it crashes. We have patched the issue in GitHub commit ad069af92392efee1418c48ff561fd3070a03d7b. The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range. There are no known workarounds for this issue.

Impact

When mlir::tfg::ConvertGenericFunctionToFunctionDef is given empty function attributes, it crashes.

Patches

We have patched the issue in GitHub commit ad069af92392efee1418c48ff561fd3070a03d7b.
