CVE-2026-9982
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 · uneditedInsufficient validation of untrusted input in ANGLE in Google Chrome prior to 148.0.7778.216 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
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.

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 if Google Chrome is installedOpen Chrome and navigate to chrome://version, or on Windows check Program Files/Google/Chrome/Application/, or on macOS check /Applications/Google Chrome.appAffected if Chrome browser is present on the system
-
Determine installed Chrome versionIn Chrome address bar, enter chrome://version and note the version number displayed (e.g., 148.0.7778.100)Affected if Unable to retrieve version number - Chrome may be blocked or inaccessible
-
Compare against affected version rangesCompare your installed version to the affected ranges: versions below 148.0.7778.216 or versions below 148.0.7778.215 are vulnerableAffected if Your Chrome version is less than 148.0.7778.216 or less than 148.0.7778.215 (note: two separate version thresholds indicate multiple affected branches)
You are affected if Google Chrome is installed and its version is below 148.0.7778.216 or below 148.0.7778.215, and an attacker has already compromised the renderer process to exploit the ANGLE validation flaw.
