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-2026-16742 in the wild and no public exploit code.\n\nAffected product: systemd-homed. 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-2026-16742/ (Markdown: https://insights.sbomify.com/CVE-2026-16742/index.md)","id":"CVE-2026-16742","markdown":"https://insights.sbomify.com/CVE-2026-16742/index.md","name":"CVE-2026-16742","record":{"aliases":["AZL-95643","DEBIAN-CVE-2026-16742","ECHO-9f82-dc11-1360","OESA-2026-3742","OESA-2026-3743","OESA-2026-3744","OESA-2026-3897","ROOT-OS-DEBIAN-13-CVE-2026-16742","UBUNTU-CVE-2026-16742"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"systemd-homed","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges by adding arbitrary system groups to homed-managed users due to missing signature verification.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"systemd","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-347","name":"Improper Verification of Cryptographic Signature"},{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"systemd-homed contains a local privilege escalation bug via arbitrary system group addition to a local, logged in, homed-managed user","ecosystems":[],"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-homed: local privilege escalation via missing home-record signature verification on the authenticate path","id":"CVE-2026-16742","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Accountsservice: accountsservice: arbitrary file read via seticonfile for systemd-homed users","id":"CVE-2026-16743"},"packages":[],"prev":{"headline":"OS Command in TR7 Cyber ​​Defense's TR7 ASP","id":"CVE-2026-16741"},"products":["systemd-homed"],"published":"2026-08-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-08-10","vendors":["systemd"]},"summary":"Local attackers can escalate privileges by adding arbitrary system groups to homed-managed users due to missing signature verification.","url":"https://insights.sbomify.com/CVE-2026-16742/"}
