Summary

In libinput before 1.30.4 and 1.31.x before 1.31.3, libinput-device-group unescaped phys output can inject udev properties leading to arbitrary root code execution.

Risk Assessment

An attacker can gain full root control over the system by injecting udev properties, potentially leading to complete system compromise.

Recommendation

Upgrade libinput to version 1.30.4 or 1.31.3, which include a fix for escaping phys output.

Other vulnerabilities in libinput

CVE-2026-35093High
A flaw was found in libinput that allows a local attacker to bypass security restrictions by placing a specially crafted Lua bytecode file in certain system or user configuration directories. The attacker can run unauthorized code with the same permissions as the program using libinput, such as a graphical compositor. This could lead to monitoring keyboard input and sending that information to an external location.
