AVID-2026-R1027
Description
Missing validation causes denial of service in TensorFlow via Conv3DBackpropFilterV2 (CVE-2022-29204)
Details
TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, the implementation of tf.raw_ops.UnsortedSegmentJoin does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack. The code assumes num_segments is a positive scalar but there is no validation. Since this value is used to allocate the output tensor, a negative value would result in a CHECK-failure (assertion failure), as per TFSA-2021-198. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.
Reason for inclusion in AVID: CVE-2022-29204 describes a vulnerability in TensorFlow where missing input validation leads to a denial-of-service via a specific operation. TensorFlow is a core ML framework used in AI pipelines; the issue is in a software component (library/framework) used to build/train/run general-purpose AI systems, representing a software supply-chain vulnerability affecting AI software stacks. It is a security vulnerability (DoS) with explicit CVE references.
