It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-29111 in the wild and no public exploit code.\n\nAffected product: Systemd Project Systemd. 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-2026-29111/ (Markdown: https://insights.sbomify.com/CVE-2026-29111/index.md)","id":"CVE-2026-29111","markdown":"https://insights.sbomify.com/CVE-2026-29111/index.md","name":"CVE-2026-29111","record":{"aliases":["ALSA-2026:13651","ALSA-2026:13677","ALSA-2026:19068","ALSA-2026:19213","AZL-80538","AZL-80937","CLSA-2026-1777482797","CLSA-2026-1779217317","CLSA-2026-1784813417","CLSA-2026-1784813597","CLSA-2026-1784813658","CLSA-2026-1787401254","DEBIAN-CVE-2026-29111","ECHO-bf64-f9b5-3e12","GHSA-gx6q-6f99-m764","OESA-2026-2122","OESA-2026-2123","RHSA-2026:13651","RHSA-2026:13677","RHSA-2026:19068","RHSA-2026:19213","RHSA-2026:25900","RHSA-2026:49910","RHSA-2026:50050","RHSA-2026:50051","RHSA-2026:50077","RHSA-2026:51134","RHSA-2026:51277","RLSA-2026:13651","RLSA-2026:13677","RLSA-2026:19068","RLSA-2026:19213"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"systemd service manager","requires_auth":"low_privilege","summary":"A local unprivileged user can trigger an assertion failure in systemd, causing the system to freeze and resulting in a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"systemd","vendor":"systemd_project"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"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.
