Background
TensorFlow is an open-source machine learning library developed by Google, widely used for building and training machine learning models. It provides a flexible architecture and a comprehensive ecosystem for various applications, including deep learning and neural networks. However, TensorFlow has been found to have a vulnerability in the AudioSummaryV2 function, which can lead to denial of service attacks if exploited.
Vulnerability Detail
The vulnerability arises when the AudioSummaryV2 function receives an input sample_rate with more than one element. This condition triggers a CHECK failure, which can be exploited to cause a denial of service. An attacker could craft a specific input that leads to this failure, effectively disrupting the service and making it unavailable to legitimate users. The technical details indicate that the vulnerability is present in TensorFlow versions prior to 2.7.2, 2.8.1, and 2.9.1.
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.
If you can't move to the latest
The minimum fixed version depends on the release line you run.

Workaround
As a temporary workaround, avoid using the AudioSummaryV2 function with a sample_rate that contains more than one element. Here is an example of how to correctly use the function with a single element sample_rate:
import tensorflow as tf arg_0='' arg_1=tf.random.uniform(shape=(1,1), dtype=tf.float32, maxval=None) arg_2=tf.constant(44100, dtype=tf.int32) # Use a single element sample rate arg_3=3 arg_4='' tf.raw_ops.AudioSummaryV2(tag=arg_0, tensor=arg_1, sample_rate=arg_2, max_outputs=arg_3, name=arg_4)
Conclusion
In summary, CVE-2022-35995 is a significant vulnerability in TensorFlow's AudioSummaryV2 function that can lead to denial of service. It is crucial for users to update to the latest patched versions to mitigate this risk. Additionally, using Vulert can help monitor and alert for such vulnerabilities in real-time.
