TensorFlow vulnerable to `CHECK` fail in `tf.linalg.matrix_rank`

TensorFlow

CVE-2022-35988 · 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

When tf.linalg.matrix_rank receives an empty input a, the GPU kernel gives a CHECK fail that can be used to trigger a denial of service attack.

```python

import tensorflow as tf

a = tf.constant([], shape=[0, 1, 1], dtype=tf.float32)

tf.linalg.matrix_rank(a=a)

`

Patches

We have patched the issue in GitHub commit [c55b476aa0e0bd4ee99d0f3ad18d9d706cd1260a](https://github.com/tensorflow/tensorflow/commit/c55b476aa0e0bd4ee99d0f3ad18d9d706cd1260a).

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.
