Mitigation checklist
- To mitigate this vulnerability, users should avoid opening untrusted web content or visiting untrusted websites. For systems where web browsing functionality is not required, consider removing packages that provide web rendering capabilities, such as `chromium` or `qt5-qtwebengine`/`qt6-qtwebengine`. Note that removing these packages may impact the functionality of other desktop applications or the desktop environment itself.
