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 confidenceUse-after-free vulnerability in Chrome's Extensions component prior to version 108.0.5359.71. An attacker tricks a user into installing a malicious extension, which combined with specific UI interaction triggers a use-after-free condition leading to potential heap corruption and arbitrary 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 installed Chrome versionNavigate to chrome://settings/help in the Chrome browser, or run 'google-chrome --version' or 'chromium --version' from command lineAffected if The displayed version number is lower than 108.0.5359.71 (for example, 107.0.5359.94 or earlier)
-
Verify Extensions component is activeOpen chrome://extensions and confirm the Extensions page loads. The Extensions component is enabled by default in standard Chrome installationsAffected if Extensions are enabled (which is the default state for typical Chrome installations)
-
Review installed extensions for untrusted sourcesNavigate to chrome://extensions and inspect all installed extensions. Check if any extension is from an unknown or untrusted developer, or was installed outside the Chrome Web StoreAffected if Any extension is installed from an untrusted or unknown source, as this increases the likelihood of encountering the malicious extension scenario described in the CVE
You are affected if your Chrome version is below 108.0.5359.71 AND you have extensions enabled, particularly if any untrusted extensions are installed.
