A serious security bug is in the news. How do I know whether to worry?

Reviewed answer

Check your exact product, version, and the maker's instructions before deciding the news applies.

Write down your device model and installed software version.
Read the maker's security notice for affected versions, the fixed version, and any confirmed attacks.
Install the official fix if needed. If none exists, follow the maker's specific temporary advice instead of a social-media workaround.

Your version is affected and remains exposed. A high severity score alone does not show that you were targeted.
