Background

TensorFlow is an end-to-end open source platform for machine learning. It provides a comprehensive ecosystem of tools, libraries, and resources for developing and deploying machine learning models. TensorFlow GPU is a variant of TensorFlow that leverages GPU acceleration for faster computation. It is widely used in various industries and research domains for training and inference of deep learning models.

Vulnerability Detail

The vulnerability (CVE-2021-29594) exists in the convolution code of TensorFlow Lite (TFLite). The affected code, located in the 'conv.cc' file, performs multiple divisions where the divisor is controlled by the user and not checked for non-zero values. This oversight can lead to a division by zero error, causing the program to crash or exhibit unexpected behavior. An attacker could potentially exploit this vulnerability to cause a denial-of-service (DoS) attack or execute arbitrary code.

How To Fix

Latest published version: 2.12.0 as of 22 Oct 2026

pip install --upgrade "tensorflow-gpu==2.12.0"

Upgrading to it may include breaking changes; the versions below are the minimum fixed release for this vulnerability.
