CVE-2022-36026

Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.10.0 TensorFlow versions 2.9.1 and earlier TensorFlow versions 2.8.1 and earlier TensorFlow versions 2.7.2 and earlier

Description The issue arises when the QuantizeAndDequantizeV3 function is given a nonscalar num bits input tensor, resulting in a CHECK fail that can be used to trigger a denial of service attack. There are no known workarounds for this issue.

Recommendations For versions prior to 2.10.0, update to TensorFlow 2.10.0 or later. For versions 2.9.1 and earlier, update to TensorFlow 2.9.1 or later. For versions 2.8.1 and earlier, update to TensorFlow 2.8.1 or later. For versions 2.7.2 and earlier, update to TensorFlow 2.7.2 or later. As a temporary workaround, consider avoiding the use of the QuantizeAndDequantizeV3 function with nonscalar num bits input tensors until a patch is available.
