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)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"systemd","purl":"pkg:rpm/openEuler/systemd&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"243-88.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["systemd-243-88.oe2003sp4.aarch64.rpm","systemd-container-243-88.oe2003sp4.aarch64.rpm","systemd-debuginfo-243-88.oe2003sp4.aarch64.rpm","systemd-debugsource-243-88.oe2003sp4.aarch64.rpm","systemd-devel-243-88.oe2003sp4.aarch64.rpm","systemd-journal-remote-243-88.oe2003sp4.aarch64.rpm","systemd-libs-243-88.oe2003sp4.aarch64.rpm","systemd-udev-243-88.oe2003sp4.aarch64.rpm","systemd-udev-compat-243-88.oe2003sp4.aarch64.rpm"],"noarch":["systemd-help-243-88.oe2003sp4.noarch.rpm"],"src":["systemd-243-88.oe2003sp4.src.rpm"],"x86_64":["systemd-243-88.oe2003sp4.x86_64.rpm","systemd-container-243-88.oe2003sp4.x86_64.rpm","systemd-debuginfo-243-88.oe2003sp4.x86_64.rpm","systemd-debugsource-243-88.oe2003sp4.x86_64.rpm","systemd-devel-243-88.oe2003sp4.x86_64.rpm","systemd-journal-remote-243-88.oe2003sp4.x86_64.rpm","systemd-libs-243-88.oe2003sp4.x86_64.rpm","systemd-udev-243-88.oe2003sp4.x86_64.rpm","systemd-udev-compat-243-88.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1912"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-4105"}],"database_specific":{"severity":"Medium"}}
