CVE-2026-9967
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 write in GPU in Google Chrome prior to 148.0.7778.216 allowed a remote attacker 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.
dbcve analysis · high confidenceAn out-of-bounds write vulnerability in Google Chrome's GPU process allows a remote attacker to execute arbitrary code via a malicious HTML page. The flaw can potentially enable sandbox escape, granting the attacker elevated privileges beyond the browser's security boundaries.

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.
-
Determine installed Chrome versionNavigate to chrome://version in the Chrome address bar and note the version number shown in the 'Google Chrome' field, or click Help > About Google ChromeAffected if The installed version is less than 148.0.7778.216
-
Confirm GPU rendering is enabledNavigate to chrome://gpu and look for 'Graphics Feature Status' section; check if 'GPU process' shows as enabled, or enter chrome://settings and search for 'Hardware acceleration' to verify it is turned onAffected if GPU rendering is enabled (this is the default and typical configuration)
-
Verify the specific affected minor versionsReview the exact version number against both affected ranges: versions below 148.0.7778.216 and versions below 148.0.7778.215Affected if The version is below both 148.0.7778.215 and 148.0.7778.216 (note: 148.0.7778.215 is also listed as an affected version)
The user is affected if they are running any Google Chrome version below 148.0.7778.216 with GPU hardware acceleration enabled (the default state).
