Heap buffer overflow in GPU

CVE-2022-4135GHSA-995f-9x5r-2rcj

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (electron 19.1.8), 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.

# Patch Next advisory brief: CVE-2022-4135

Advisory: Heap buffer overflow in GPU
IDs: CVE-2022-4135, GHSA-995f-9x5r-2rcj
Record: https://patchnext.com/advisories/cve-2022-4135 (revision 3, source checked 26 Oct 2026, 12:22 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.6)
Exploitation: confirmed: listed in the CISA Known Exploited Vulnerabilities catalog.
Vendor response: Vendor fix available; fixed versions by package: electron 19.1.8. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm electron: affected >= 19.0.0, < 19.1.8; fixed in 19.1.8

## Suggested inspection (read-only)
- `npm ls electron --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## 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 electron.
- 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?
- Mark the work resolved only after the fixed version is verified in production.
