    CVE-2022-29202

    Published: 20 May 2022Last Modified: 12 Aug 2026

    Summary: Denial of service in TensorFlow due to lack of validation in `tf.ragged.constant`

    Details: 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, the implementation of `tf.ragged.constant` does not fully validate the input arguments. This results in a denial of service by consuming all available memory. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.
