AVID-2026-R0861

Description

Reference binding to nullptr in map operations in TensorFlow (CVE-2021-37671)

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.Map* and tf.raw_ops.OrderedMap* operations. The implementation has a check in place to ensure that indices is in ascending order, but does not check that indices is not empty. We have patched the issue in GitHub commit 532f5c5a547126c634fefd43bbad1dc6417678ac. 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: This CVE describes a vulnerability in TensorFlow, a core AI/ML framework widely used in general-purpose AI pipelines. It affects TensorFlow versions and components that are part of AI software stacks (dependencies/runtimes) and has a fix committed in the TensorFlow repo. The issue is a security vulnerability (memory access issue) with high impact, and TensorFlow is a common building block in AI systems, so it is relevant to the software supply chain of general-purpose AI systems. The report provides explicit evidence (affected versions, patch commit, references) to support classification.
