Package

pip tflite-micro (pip)

Affected versions

< 2.10.0

Patched versions

2.7.4, 2.8.3, 2.9.2, 2.10.0

Description

Impact

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.

Patches

We have patched the issue 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.
