CVE-2026-50265
Libinput: local privilege escalation via crafted uinput devices
Description
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.
