What is CVE-2026-35093?

A vulnerability in libinput allows local attackers to exploit specially crafted Lua bytecode files placed in system or user configuration directories. By doing so, they can bypass essential security restrictions, enabling the execution of unauthorized code with the same privileges as the process utilizing libinput. This presents significant risks, including the potential to monitor keystrokes and exfiltrate sensitive information to external locations.
