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-2024-21820 in the wild and no public exploit code.\n\nAffected product: Intel(R) Xeon(R) processor memory controller configurations when using Intel(R) SGX. 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-2024-21820/ (Markdown: https://insights.sbomify.com/CVE-2024-21820/index.md)","id":"CVE-2024-21820","markdown":"https://insights.sbomify.com/CVE-2024-21820/index.md","name":"CVE-2024-21820","record":{"aliases":["BELL-CVE-2024-21820","DEBIAN-CVE-2024-21820","GHSA-643q-8gx3-hf55","UBUNTU-CVE-2024-21820"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel Xeon SGX","requires_auth":"high_privilege","summary":"A privileged local user can escalate privileges due to incorrect default permissions in Intel Xeon SGX memory controller configurations.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"Incorrect default permissions in some Intel(R) Xeon(R) processor memory controller configurations when using Intel(R) SGX may allow a privileged user to potentially enable escalation of privilege via local access.","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":"Privilege escalation in Intel(R) Xeon(R) processor memory controller configurations when using Intel(R) SGX","id":"CVE-2024-21820","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in Archer AX3000","id":"CVE-2024-21821"},"packages":[],"prev":{"headline":"Privilege escalation in Intel(R) PCM software","id":"CVE-2024-21818"},"products":["Intel(R) Xeon(R) processor memory controller configurations when using Intel(R) SGX"],"published":"2024-11-13","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":"2025-11-03","vendors":["n/a"]},"summary":"A privileged local user can escalate privileges due to incorrect default permissions in Intel Xeon SGX memory controller configurations.","url":"https://insights.sbomify.com/CVE-2024-21820/"}
