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.
-
Verify Chrome is running on WindowsCheck the operating system by going to Chrome settings, clicking 'About Google Chrome', or running 'winver' in Windows Run dialog. This vulnerability only affects Windows systems.Affected if The system is not running Windows (Linux/macOS are not affected by this specific flaw).
-
Identify installed Google Chrome versionOpen Chrome, go to Menu > Help > About Google Chrome, or navigate to chrome://settings/help. Note the version number displayed.Affected if The installed version is any version prior to 147.0.7727.116 (e.g., 147.0.7727.115, 146.x.x.x, etc.).
-
Confirm GPU process is not disabledCheck Chrome startup flags by navigating to chrome://flags or reviewing any enterprise policies. Look for --disable-gpu, --disable-software-rasterizer, or similar flags that would disable the GPU process.Affected if GPU process is enabled (not explicitly disabled). If --disable-gpu flag is active, the attack surface is significantly reduced but the browser may still report the vulnerable version.
A user is affected if they are running Google Chrome on Windows with version lower than 147.0.7727.116 and the GPU process is enabled (not disabled via flags or policies).
