Description

Missing validation crashes QuantizeAndDequantizeV4Grad

Impact

The implementation of [tf.raw_ops.QuantizeAndDequantizeV4Grad](https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/quantize_and_dequantize_op.cc#L148-L226) does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack:

```python

import tensorflow as tf

tf.raw_ops.QuantizeAndDequantizeV4Grad(

gradients=tf.constant(1, shape=[2,2], dtype=tf.float64),

input=tf.constant(1, shape=[2,2], dtype=tf.float64),

input_min=tf.constant([], shape=[0], dtype=tf.float64),

input_max=tf.constant(-10, shape=[], dtype=tf.float64),

axis=-1)

```

The code assumes input_min and input_max are scalars but there is no validation for this.

Patches

We have patched the issue in GitHub commit [098e7762d909bac47ce1dbabe6dfd06294cb9d58](https://github.com/tensorflow/tensorflow/commit/098e7762d909bac47ce1dbabe6dfd06294cb9d58).

The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.

Attribution

This vulnerability has been reported by Neophytos Christou from Secure Systems Lab at Brown University.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: None.
  • Integrity impact: None.
  • Availability impact: High — total loss, or loss the attacker controls.

Weakness class

CVE-2022-29192 is classified as CWE-20: Improper Input Validation. The application accepts input without checking that it has the expected form, so malformed values reach code that assumes they are well formed.

Affected software

CVE-2022-29192 is recorded against 3 packages.

  • tensorflow (from 2.8.0 up to 2.8.1)
  • tensorflow-cpu (from 2.8.0 up to 2.8.1)
  • tensorflow-gpu (from 2.8.0 up to 2.8.1)

Timeline and source

Published on 9 July 2026 and last revised on 13 July 2026. A public exploit is known to exist, which raises the urgency of patching considerably. A vendor advisory or fix has been published. Record sourced from OSV.
