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://version in the Chrome address bar or open Chrome and go to Help > About Google Chrome. Note the version number displayed.Affected if The displayed version is lower than 126.0.6478.114 (e.g., 125.x.x.x or earlier)
-
Verify WebGPU/Dawn statusNavigate to chrome://gpu in Chrome and look for the WebGPU or Dawn entry in the Graphics Feature Status section. Alternatively, search for 'WebGPU' on this page.Affected if WebGPU/Dawn is listed as enabled or hardware-accelerated (the vulnerable code path is active when WebGPU is functional)
-
Confirm Chrome channelOpen chrome://version and check if the version string includes 'Dev', 'Beta', or other channel indicators, or check Help > About Google Chrome to see the update channel.Affected if Using Chrome Dev, Beta, or stable channel versions prior to 126.0.6478.114 - all channels below this version are affected
You are affected if your Chrome version is any release prior to 126.0.6478.114 AND WebGPU functionality is available/enabled in your browser.
