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 or use 'About Google Chrome' from the Chrome menu to view the current version numberAffected if Version displayed is earlier than 146.0.7680.71 (for example, 146.0.7680.50 or any version below 146.0.7680.71)
-
Verify WebML component statusNavigate to chrome://flags/#web-machine-learning and check whether the WebML flag is enabled or disabledAffected if WebML feature is set to Enabled, making the vulnerable code path accessible
-
Confirm Chrome channelCheck if Chrome is running in Stable, Beta, Dev, or Canary channel via chrome://settings/helpAffected if Running an older stable or beta channel version that has not yet received the 146.0.7680.71 update
You are affected if Chrome version is below 146.0.7680.71 AND the WebML feature is enabled, allowing the heap buffer overflow in the WebML component to be triggered through a malicious HTML page.
