Doc Text:
A flaw was found in libinput. A local attacker with access to /dev/uinput can inject arbitrary udev properties through the libinput-device-group helper. This injection can lead to root code execution, for example, by exploiting REMOVE_CMD properties that are executed when a device is removed. This vulnerability allows an attacker to gain elevated privileges on the system.

Description OSIDB Bzimport 2026-06-05 08:18:25 UTC
A local attacker with /dev/uinput access can inject arbitrary udev properties through the libinput-device-group helper. Depending on downstream udev rules, this can result in root code execution (e.g. via injected REMOVE_CMD properties
executed at device removal time). REMOVE_CMD is in the default udev rules and expected to be present on virtually all machines.
