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 Google Chrome is installedCheck for Chrome executable: on Windows look in Program Files/Google/Chrome/Application/chrome.exe, on Linux check /usr/bin/google-chrome or /opt/google/chrome/google-chrome, on macOS check /Applications/Google Chrome.appAffected if Chrome browser is present on the system
-
Determine installed Chrome versionOpen Chrome and navigate to chrome://version, or run 'google-chrome --version' from command line on Linux, or right-click the Chrome shortcut and select Properties on WindowsAffected if Version number is lower than 126.0.6478.54
-
Confirm operating system is Fedora 39 or 40Run 'cat /etc/fedora-release' or 'cat /etc/os-release' from terminalAffected if System runs Fedora 39 or Fedora 40 and has Chrome installed
-
Identify PDF viewer usageThis vulnerability affects Chrome's built-in PDF viewer when processing audio content within PDF files; no additional feature check needed as PDF viewing is integrated into ChromeAffected if User opens PDF files in Chrome (default behavior)
User is affected if Google Chrome version is below 126.0.6478.54 and they open crafted PDF files containing malicious audio content in the browser's PDF viewer.
