CVE-2026-4440
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOut of bounds read and write in WebGL in Google Chrome prior to 146.0.7680.153 allowed a remote attacker to perform arbitrary read/write via a crafted HTML page. (Chromium security severity: Critical)
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOut of bounds memory read and write vulnerability in the WebGL implementation in Google Chrome prior to version 146.0.7680.153 allows remote attackers to perform arbitrary memory read/write operations via a specially crafted HTML page, potentially leading to code execution or data exfiltration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Google Chrome versionOpen Chrome and navigate to chrome://version, or click the three-dot menu > Help > About Google Chrome. The version number is displayed at the top.Affected if The displayed version is less than 146.0.7680.153 (e.g., 146.0.7680.100, 145.x.x.x, etc.)
-
Confirm WebGL is enabledNavigate to chrome://flags in the address bar and search for 'WebGL' or go to chrome://settings and check content settings under Graphics. Alternatively, open the JavaScript console on any page and run: 'console.log(HTMLCanvasElement.prototype.getContext("webgl") ? "WebGL available" : "WebGL not available");'Affected if WebGL is enabled or available in the browser profile being tested
-
Verify the vulnerability window existsCompare your installed version number (from step 1) against the affected range: any version prior to 146.0.7680.153 is affected.Affected if Your Chrome version falls below 146.0.7680.153 AND WebGL is enabled
You are affected if you are running Google Chrome with WebGL enabled and the installed version is lower than 146.0.7680.153.
