USN-5382-1: libinput vulnerability

20 April 2022

libinput could be made to crash or expose sensitive information.



  • libinput - Input device management and event handling library


Albin Eldstål-Ahrens and Lukas Lamster discovered libinput did not properly
handle input devices with specially crafted names. A local attacker with
physical access could use this to cause libinput to crash or expose
sensitive information.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 21.10
Ubuntu 20.04
Ubuntu 18.04

After a standard system update you need to log out of all desktop sessions
and then log back in to make all the necessary changes.
