Amazon Linux 2023 : libinput, libinput-devel, libinput-test (ALAS2023-2026-1857)

critical Nessus Plugin ID 321997

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1857 advisory.

 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. (CVE-2026-50265)

 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 (CVE-2026-50292)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update libinput --releasever 2023.12.20260622' or or 'dnf update --advisory ALAS2023-2026-1857 --releasever 2023.12.20260622' to update your system.
