Integer Overflow or Wraparound in TensorFlow

GHSA-wcv5-vrvr-3rx2

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (tensorflow 2.7.1, 2.6.3, 2.5.3; tensorflow-gpu 2.7.1, 2.6.3, 2.5.3; tensorflow-cpu 2.7.1, 2.6.3, 2.5.3), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Impact The Grappler component of TensorFlow is vulnerable to a denial of service via CHECK-failure (assertion failure) in constant folding: The outputprop tensor has a shape that is controlled by user input and this can result in triggering one of the CHECKs in the PartialTensorShape constructor. This is an instance of TFSA-2021-198 (CVE-2021-41197). Patches We have patched the issue in GitHub commit be7b286d40bc68cb0b56f702186cc4837d508058. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

# Patch Next advisory brief: GHSA-wcv5-vrvr-3rx2

Advisory: Integer Overflow or Wraparound in TensorFlow
IDs: GHSA-wcv5-vrvr-3rx2
Record: https://patchnext.com/advisories/ghsa-wcv5-vrvr-3rx2 (revision 2, source checked 26 Oct 2026, 13:08 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: tensorflow 2.7.1, 2.6.3, 2.5.3; tensorflow-gpu 2.7.1, 2.6.3, 2.5.3; tensorflow-cpu 2.7.1, 2.6.3, 2.5.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI tensorflow: affected < 2.5.3; >= 2.6.0, < 2.6.3; >= 2.7.0, <= 2.7.0; fixed in 2.5.3, 2.7.1, 2.6.3
- PyPI tensorflow-gpu: affected < 2.5.3; >= 2.6.0, < 2.6.3; >= 2.7.0, <= 2.7.0; fixed in 2.5.3, 2.7.1, 2.6.3
- PyPI tensorflow-cpu: affected < 2.5.3; >= 2.6.0, < 2.6.3; >= 2.7.0, <= 2.7.0; fixed in 2.5.3, 2.7.1, 2.6.3

## Suggested inspection (read-only)
- `python -m pip show tensorflow`: prints the installed version. Run with the environment that serves production active.
- `python -m pip show tensorflow-gpu`: prints the installed version. Run with the environment that serves production active.
- `python -m pip show tensorflow-cpu`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on tensorflow, tensorflow-gpu, tensorflow-cpu.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
