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-2020-8991 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-8991/ (Markdown: https://insights.sbomify.com/CVE-2020-8991/index.md)","id":"CVE-2020-8991","markdown":"https://insights.sbomify.com/CVE-2020-8991/index.md","name":"CVE-2020-8991","record":{"aliases":["DEBIAN-CVE-2020-8991","GHSA-qhfv-hfvw-jqhq"],"analysis":{"component_type":"operating_system","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"LVM2 logical volume manager","requires_auth":"high_privilege","summary":"A memory leak in LVM2's lvmetad daemon could potentially lead to resource exhaustion, though its security impact is disputed.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lvm2","vendor":"redhat"}],"cvss":{"score":2.3,"severity":"low","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"vg_lookup in daemons/lvmetad/lvmetad-core.c in LVM2 2.02 mismanages memory, leading to an lvmetad memory leak, as demonstrated by running pvs. NOTE: RedHat disputes CVE-2020-8991 as not being a vulnerability since there’s no apparent route to either privilege escalation or to denial of service through the bug","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":"Denial of service in n/a","id":"CVE-2020-8991","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-8992"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2020-8990"},"products":["n/a"],"published":"2020-02-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"partial"},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A memory leak in LVM2's lvmetad daemon could potentially lead to resource exhaustion, though its security impact is disputed.","url":"https://insights.sbomify.com/CVE-2020-8991/"}
