Q: Is this vulnerability actively exploited?

A: Debian has not confirmed in-the-wild attacks, but zero-day risks justify immediate patching.

Q: Does this affect Chromium forks like Brave or Vivaldi?

A: Yes, if they’re based on unpatched Chromium builds. Check your browser’s version.

Q: How does this compare to recent Chrome updates?

A: Google’s closed-source Chrome typically patches faster; open-source Chromium relies on distro maintainers like Debian.
