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:22.03-LTS-SP4","name":"systemd","purl":"pkg:rpm/openEuler/systemd&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"249-112.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["systemd-249-112.oe2203sp4.aarch64.rpm","systemd-container-249-112.oe2203sp4.aarch64.rpm","systemd-cryptsetup-249-112.oe2203sp4.aarch64.rpm","systemd-debuginfo-249-112.oe2203sp4.aarch64.rpm","systemd-debugsource-249-112.oe2203sp4.aarch64.rpm","systemd-devel-249-112.oe2203sp4.aarch64.rpm","systemd-libs-249-112.oe2203sp4.aarch64.rpm","systemd-networkd-249-112.oe2203sp4.aarch64.rpm","systemd-nspawn-249-112.oe2203sp4.aarch64.rpm","systemd-pam-249-112.oe2203sp4.aarch64.rpm","systemd-resolved-249-112.oe2203sp4.aarch64.rpm","systemd-timesyncd-249-112.oe2203sp4.aarch64.rpm","systemd-udev-249-112.oe2203sp4.aarch64.rpm"],"noarch":["systemd-help-249-112.oe2203sp4.noarch.rpm"],"src":["systemd-249-112.oe2203sp4.src.rpm"],"x86_64":["systemd-249-112.oe2203sp4.x86_64.rpm","systemd-container-249-112.oe2203sp4.x86_64.rpm","systemd-cryptsetup-249-112.oe2203sp4.x86_64.rpm","systemd-debuginfo-249-112.oe2203sp4.x86_64.rpm","systemd-debugsource-249-112.oe2203sp4.x86_64.rpm","systemd-devel-249-112.oe2203sp4.x86_64.rpm","systemd-libs-249-112.oe2203sp4.x86_64.rpm","systemd-networkd-249-112.oe2203sp4.x86_64.rpm","systemd-nspawn-249-112.oe2203sp4.x86_64.rpm","systemd-pam-249-112.oe2203sp4.x86_64.rpm","systemd-resolved-249-112.oe2203sp4.x86_64.rpm","systemd-timesyncd-249-112.oe2203sp4.x86_64.rpm","systemd-udev-249-112.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1913"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-4105"}],"database_specific":{"severity":"Medium"}}
