AVID-2026-R1063

Description

OOB read in Gather_nd op in TensorFlow Lite Micro (CVE-2022-35938)

Details

TensorFlow is an open source platform for machine learning. The GatherNd function takes arguments that determine the sizes of inputs and outputs. If the inputs given are greater than or equal to the sizes of the outputs, an out-of-bounds memory read or a crash is triggered. This issue has been patched in GitHub commit 4142e47e9e31db481781b955ed3ff807a781b494. The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range. There are no known workarounds for this issue.

Reason for inclusion in AVID: The report describes a CVE affecting TensorFlow Lite Micro’s Gather_nd op, an AI framework component. This is a software vulnerability in a general-purpose AI stack, with implications for deployment in AI systems. It concerns a dependency/framework used to run ML workloads, thus relevant to the AI supply chain. The CVE includes patch information and references, providing sufficient evidence.
