CVE-2022-23592: Out of bounds read in Tensorflow

Severity: high (CVSS 8.1 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.9% probability of exploitation in the next 30 days
Public exploit or detection template: yes
Published: 2022-02-04 · updated 2026-06-17
Weakness: CWE-125

Description

Tensorflow is an Open Source Machine Learning Framework. TensorFlow's type inference can cause a heap out of bounds read as the bounds checking is done in a `DCHECK` (which is a no-op during production). An attacker can control the `input_idx` variable such that `ix` would be larger than the number of values in `node_t.args`. The fix will be included in TensorFlow 2.8.0. This is the only affected version.

Affected products

tensorflow: from 2.7.0 before 2.8.0 — fixed in 2.8.0

How to fix

Upgrade to a fixed version: tensorflow 2.8.0. Check the vendor advisory for mitigations.
