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-2021-4210 in the wild and no public exploit code.\n\nAffected product: Lenovo BIOS. 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-2021-4210/ (Markdown: https://insights.sbomify.com/CVE-2021-4210/index.md)","id":"CVE-2021-4210","markdown":"https://insights.sbomify.com/CVE-2021-4210/index.md","name":"CVE-2021-4210","record":{"aliases":["GHSA-2gc6-xpq3-f7gm"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lenovo BIOS","requires_auth":"high_privilege","summary":"Local attackers with elevated privileges can execute arbitrary code via a vulnerability in the NVME driver SMI callback function in Lenovo BIOS.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"a540-24icb_firmware","vendor":"lenovo"},{"product":"a540-27icb_firmware","vendor":"lenovo"},{"product":"ideacentre_5-14imb05_firmware","vendor":"lenovo"},{"product":"ideacentre_aio_3-22ada6_firmware","vendor":"lenovo"},{"product":"ideacentre_aio_3-22iil5_firmware","vendor":"lenovo"},{"product":"ideacentre_aio_3-22itl6_firmware","vendor":"lenovo"},{"product":"ideacentre_aio_3-24ada6_firmware","vendor":"lenovo"},{"product":"ideacentre_aio_3-24iil5_firmware","vendor":"lenovo"},{"product":"ideacentre_aio_3-24itl6_firmware","vendor":"lenovo"},{"product":"ideacentre_aio_3-27itl6_firmware","vendor":"lenovo"},{"product":"ideacentre_c5-14imb05_firmware","vendor":"lenovo"},{"product":"ideacentre_g5-14imb05_firmware","vendor":"lenovo"},{"product":"stadia_ggp-120_firmware","vendor":"lenovo"},{"product":"thinkcentre_m700_firmware","vendor":"lenovo"},{"product":"thinkcentre_m700_tiny_firmware","vendor":"lenovo"},{"product":"thinkcentre_m70a_firmware","vendor":"lenovo"},{"product":"thinkcentre_m75n_firmware","vendor":"lenovo"},{"product":"thinkcentre_m800_firmware","vendor":"lenovo"},{"product":"thinkcentre_m810z_firmware","vendor":"lenovo"},{"product":"thinkcentre_m820z_firmware","vendor":"lenovo"},{"product":"thinkcentre_m900_firmware","vendor":"lenovo"},{"product":"thinkcentre_m900x_firmware","vendor":"lenovo"},{"product":"thinkcentre_m90a_gen2_firmware","vendor":"lenovo"},{"product":"thinkcentre_m910z_firmware","vendor":"lenovo"},{"product":"thinkcentre_x1_firmware","vendor":"lenovo"},{"product":"thinkedge_se30_firmware","vendor":"lenovo"},{"product":"thinkstation_p310_firmware","vendor":"lenovo"},{"product":"thinkstation_p520_firmware","vendor":"lenovo"},{"product":"thinkstation_p520c_firmware","vendor":"lenovo"},{"product":"v410z_firmware","vendor":"lenovo"},{"product":"v50t-13imb_firmware","vendor":"lenovo"},{"product":"v540-24iwl_firmware","vendor":"lenovo"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A potential vulnerability in the SMI callback function used in the NVME driver in some Lenovo Desktop, ThinkStation, and ThinkEdge models may allow an attacker with local access and elevated privileges to execute arbitrary code.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Code injection in BIOS","id":"CVE-2021-4210","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in BIOS","id":"CVE-2021-4211"},"packages":[],"prev":{"headline":"Null dereference in GnuTLS","id":"CVE-2021-4209"},"products":["BIOS"],"published":"2022-04-22","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Lenovo"]},"summary":"Local attackers with elevated privileges can execute arbitrary code via a vulnerability in the NVME driver SMI callback function in Lenovo BIOS.","url":"https://insights.sbomify.com/CVE-2021-4210/"}
