Background
TensorFlow is an open-source machine learning framework developed by Google. It provides a comprehensive ecosystem of tools, libraries, and resources for building and deploying machine learning models. TensorFlow is widely used in various domains, including research, industry, and academia. However, a vulnerability has been discovered in the implementation of depthwise ops in TensorFlow, which can lead to a denial of service attack.
Vulnerability Detail
The vulnerability in TensorFlow is caused by a CHECK failure (assertion failure) in depthwise ops due to overflows. By overflowing the number of elements in a tensor, an attacker can trigger a denial of service attack. This vulnerability is another instance of TFSA-2021-198 (CVE-2021-41197). The impact of this vulnerability can be severe, as it can disrupt the availability of TensorFlow-based systems and potentially lead to further exploitation.
