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.

An attacker tricks a user into installing a malicious extension, which then uses a crafted HTML page to trigger a use-after-free condition, potentially corrupting heap memory and enabling code execution.

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 versionNavigate to chrome://version in the Chrome address bar or open Chrome and go to Help > About Google Chrome. The version number is displayed at the top of the page.Affected if The displayed version is earlier than 114.0.5735.90 (e.g., 113.0.x.x, 112.0.x.x, etc.)
-
Verify extension installation accessNavigate to chrome://extensions or go to Settings > Extensions. Look for the 'Developer mode' toggle or any extensions listed.Affected if Any untrusted or unknown extensions are installed, especially if installed outside of enterprise policy control.
-
Check for suspicious extensionsReview the list of installed extensions in chrome://extensions. Note the name, publisher, and permissions of each extension.Affected if Extensions are present that were not intentionally installed or are from untrusted sources.
