Critical vulnerabilities were disclosed in InputPlumber affecting Linux systems, including SteamOS.

Impact highlights:
• Insufficient D-Bus authorization
• Potential keystroke injection via virtual devices
• Local denial-of-service and information exposure

The fixes emphasize secure Polkit usage, systemd hardening, and proper privilege boundaries.
