Seg fault in `ndarray_tensor_bridge` due to zero and large inputs

TensorFlow

CVE-2022-41884 · Published Nov 21, 2022 · updated Jul 13, 2026

Medium4.8
Fix: upgrade to 2.8.4 or later (3 fixed versions below)
GitHub advisory

Impact

If a numpy array is created with a shape such that one element is zero and the others sum to a large number, an error will be raised. E.g. the following raises an error:

```python

np.ones((0, 231, 231))

`

An example of a proof of concept:

```python

import numpy as np

import tensorflow as tf

input_val = tf.constant([1])

shape_val = np.array([i for i in range(21)])

tf.broadcast_to(input=input_val,shape=shape_val)

`

The return value of PyArray_SimpleNewFromData, which returns null on such shapes, is not checked.

Patches

We have patched the issue in GitHub commit [2b56169c16e375c521a3bc8ea658811cc0793784](https://github.com/tensorflow/tensorflow/commit/2b56169c16e375c521a3bc8ea658811cc0793784).

The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.
