Background
TensorFlow is an open-source machine learning library that provides a comprehensive ecosystem for building and deploying machine learning models. It is widely used for various applications, including deep learning and neural networks. However, TensorFlow has a vulnerability in the TensorSummaryV2 operation, which can lead to a denial of service due to insufficient input validation.
Vulnerability Detail
The vulnerability arises from the implementation of the tf.raw_ops.TensorSummaryV2 function, which fails to fully validate its input arguments. Specifically, it assumes that the 'axis' parameter is a scalar without performing any checks. This oversight can lead to a CHECK-failure, allowing an attacker to exploit the function and trigger a denial of service attack. The vulnerability can be exploited by passing malformed input, causing the application to crash.
How To Fix
Latest published version: 2.21.0 as of 22 Oct 2026
pip install --upgrade "tensorflow==2.21.0"Upgrading to it may include breaking changes; the versions below are the minimum fixed release for this vulnerability.

Workaround
As a temporary workaround, avoid using the TensorSummaryV2 operation with unvalidated input. Ensure that the inputs passed to this function are properly validated before calling it. For example, you can check if the 'axis' parameter is a scalar before invoking the function.
Conclusion
The CVE-2022-29193 vulnerability in TensorFlow poses a risk of denial of service due to inadequate input validation in the TensorSummaryV2 operation. Users are advised to update to the latest patched versions to mitigate this risk and ensure the stability of their applications.
