Widely-Used libinput Updated Due To Arbitrary Root Code Execution Written by Michael Larabel in Desktop on 3 June 2026 at 09:46 PM EDT. Add A Comment The libinput input handling library used by both X.Org and Wayland environments on modern Linux desktops is out with a new security fix release. A new vulnerability is now public allowing for arbitrary root code execution. Libinput maintainer Peter Hutterer announced the new libinput security advisory for the issue uncovered by Csome. Due to libinput's libinput-device-group udev helper handling, a malicious uinput or uhid device could set a PHYS sysattr containing a "\n" to cause the resulting output to be interpreted as two separate key-value pairs by udev. In turn this could ultimately lead to arbitrary root code execution.
