EulerOS 2.0 SP11 : systemd (EulerOS-SA-2026-2266)

medium Nessus Plugin ID 319955

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the systemd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known workarounds are available.(CVE-2026-29111)

 A flaw was found in systemd. The systemd-machined service contains an Improper Access Control vulnerability due to insufficient validation of the class parameter in the RegisterMachine D-Bus (Desktop Bus) method. A local unprivileged user can exploit this by attempting to register a machine with a specific class value, which may leave behind a usable, attacker-controlled machine object. This allows the attacker to invoke methods on the privileged object, leading to the execution of arbitrary commands with root privileges on the host system.(CVE-2026-4105)

Tenable has extracted the preceding description block directly from the EulerOS systemd security advisory.

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

Solution

Update the affected systemd packages.
