    Package        : libinput
    Version        : 1.16.4-3+deb11u1
    CVE ID         : CVE-2022-1215 CVE-2026-50292

    Two vulnerabilities were found in libinput, an input device management
    and event handling library.

    CVE-2022-1215

        libinput did not properly handled evdev devices, which may potentially be
        exploited by malicious local users in specific setup to execute arbitrary
        code. Reported by Albin Eldstl-Ahrens and Lukas Lamster.

    CVE-2026-50292

        A udev helper provided by libinput performed insufficient sanitising of
        device properties, which can result in local privilege escalation in
        some setups. Reported by Csome.

    For Debian 11 bullseye, these problems have been fixed in version
    1.16.4-3+deb11u1.

    We recommend that you upgrade your libinput packages.
