It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-4105 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-4105/ (Markdown: https://insights.sbomify.com/CVE-2026-4105/index.md)","id":"CVE-2026-4105","markdown":"https://insights.sbomify.com/CVE-2026-4105/index.md","name":"CVE-2026-4105","record":{"aliases":["CLSA-2026-1776345550","DEBIAN-CVE-2026-4105","ECHO-230a-8355-8606","GHSA-4h6x-r8vx-3862","OESA-2026-1912","OESA-2026-1913","SUSE-SU-2026:0991-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"systemd service","requires_auth":"low_privilege","summary":"A local unprivileged user can escalate privileges to root by exploiting improper access control in the systemd-machined D-Bus method.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"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.","ecosystems":["SUSE:Linux Enterprise Server 12 SP5-LTSS","SUSE:Linux Enterprise Server LTSS Extended Security 12 SP5"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Systemd: systemd: privilege escalation via improper access control in registermachine d-bus method","id":"CVE-2026-4105","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":2,"n_references":4,"next":{"headline":"HT Mega \u003c 3.0.7 – Unauthenticated PII Disclosure","id":"CVE-2026-4106"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Server 12 SP5-LTSS","fixed":["228-157.75.1"],"introduced":["0"],"last_affected":[],"package":"systemd","purl":"pkg:rpm/suse/systemd\u0026distro=SUSE%20Linux%20Enterprise%20Server%2012%20SP5-LTSS","source":"SUSE-SU-2026:0991-1"},{"ecosystem":"SUSE:Linux Enterprise Server LTSS Extended Security 12 SP5","fixed":["228-157.75.1"],"introduced":["0"],"last_affected":[],"package":"systemd","purl":"pkg:rpm/suse/systemd\u0026distro=SUSE%20Linux%20Enterprise%20Server%20LTSS%20Extended%20Security%2012%20SP5","source":"SUSE-SU-2026:0991-1"}],"prev":{"headline":"SQLi in Akmer Informatics' TeknoPass","id":"CVE-2026-4104"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat Hardened Images","Red Hat OpenShift Container Platform 4"],"published":"2026-03-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-01","vendors":["Red Hat"]},"summary":"A local unprivileged user can escalate privileges to root by exploiting improper access control in the systemd-machined D-Bus method.","url":"https://insights.sbomify.com/CVE-2026-4105/"}
