Background
TensorFlow is an open-source machine learning framework widely used for developing and deploying machine learning models. It provides a comprehensive ecosystem for building and training neural networks. TensorFlow CPU is a specific package within TensorFlow that focuses on running TensorFlow models on CPUs. It is commonly used in scenarios where GPU acceleration is not available or required. TensorFlow CPU allows users to leverage the power of TensorFlow on CPU-only systems.
Vulnerability Detail
The simplifyBroadcast function in the MLIR-TFRT infrastructure in TensorFlow CPU is vulnerable to a denial of service (DoS) attack. This vulnerability occurs when the function is called with scalar shapes. If all shapes are scalar, the maxRank value becomes 0, resulting in the creation of an empty SmallVector. This leads to a segmentation fault, causing the application to crash and become unresponsive. The impact of this vulnerability is a complete disruption of service, rendering the affected TensorFlow CPU instance unusable.
How To Fix
Latest published version: 2.21.0 as of 22 Oct 2026
pip install --upgrade "tensorflow-cpu==2.21.0"Upgrading to it may include breaking changes; the version below is the minimum fixed release for this vulnerability.

Workaround
There is no known workaround for this vulnerability. It is essential to apply the recommended fix by upgrading to TensorFlow CPU 2.8.0 or later to mitigate the risk of a denial of service attack.
Conclusion
The vulnerability in TensorFlow CPU (CVE-2022-23593) poses a significant risk of denial of service (DoS) attacks. It is crucial for users to upgrade to TensorFlow CPU 2.8.0 or later to ensure the proper handling of scalar shapes and prevent the application from crashing. Applying the recommended fix will mitigate the risk and maintain the stability and availability of TensorFlow CPU instances.
