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.
-
Confirm Google Chrome is installedCheck for chrome executable: Windows - 'where chrome' or C:\Program Files\Google\Chrome\Application\chrome.exe; Linux - 'which google-chrome'; macOS - check /Applications/Google Chrome.appAffected if Google Chrome is not found on the system, then this CVE does not apply
-
Retrieve the installed Chrome versionNavigate to chrome://version in the Chrome browser, or run 'google-chrome --version' on Linux, or right-click Google Chrome in Applications and select Get Info on macOSAffected if Unable to determine the installed version, cannot assess exposure
-
Compare installed version against vulnerable rangeCompare the full version number (e.g., 115.0.5790.169) to 115.0.5790.170 - the vulnerability affects versions LOWER than 115.0.5790.170Affected if Installed version is 114.x.x.x or lower, or any version below 115.0.5790.170 - the environment is affected
-
Verify Blink rendering engine is in useThis is automatic in Google Chrome - the Blink engine handles HTML page rendering by default. No manual check needed unless using a Chromium-based alternative that disables BlinkAffected if Using a Chromium variant that has disabled Blink - in standard Google Chrome, Blink is always active
If Google Chrome is installed and its version is below 115.0.5790.170, the environment is vulnerable to this use-after-free flaw in the Blink Task Scheduling component.
