AVID-2026-R0866

Description

Reference binding to nullptr in shape inference in TensorFlow (CVE-2021-37676)

Details

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can cause undefined behavior via binding a reference to null pointer in tf.raw_ops.SparseFillEmptyRows. The shape inference implementation does not validate that the input arguments are not empty tensors. We have patched the issue in GitHub commit 578e634b4f1c1c684d4b4294f9e5281b2133b3ed. The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.

Reason for inclusion in AVID: CVE-2021-37676 targets TensorFlow, a core AI framework. It is a software vulnerability in a widely used dependency that directly affects AI pipelines (model training/inference) and can impact general-purpose AI systems. The report provides explicit vulnerability details, affected versions, a fix, and CVSS metrics, satisfying sufficiency for AVID curation.
