TensorFlow vulnerable to OOB read in `Gather_nd` in TF Lite

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 is triggered.

Patches

We have patched the issue in GitHub commit 595a65a3e224a0362d7e68c2213acfc2b499a196.

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.
