An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-39994 in the wild and no public exploit code.\n\nAffected product: Huawei Emui. 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-2021-39994/ (Markdown: https://insights.sbomify.com/CVE-2021-39994/index.md)","id":"CVE-2021-39994","markdown":"https://insights.sbomify.com/CVE-2021-39994/index.md","name":"CVE-2021-39994","record":{"aliases":["GHSA-ccp4-hvpw-9jmf"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Huawei EMUI","requires_auth":"none","summary":"An arbitrary address access vulnerability in Huawei EMUI test code allows attackers to compromise service confidentiality, integrity, and availability.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"emui","vendor":"huawei"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"There is an arbitrary address access vulnerability with the product line test code.Successful exploitation of this vulnerability may affect service confidentiality, integrity, and availability.","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":"Memory corruption in EMUI","id":"CVE-2021-39994","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"huawei:emui","products":["huawei:emui"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in eCNS280 TD;eSE620X vESS","id":"CVE-2021-39995"},"packages":[],"prev":{"headline":"Integer overflow in EMUI;Magic UI","id":"CVE-2021-39993"},"products":["EMUI"],"published":"2022-02-09","related":[{"cvss_score":9.8,"headline":"Memory corruption in EMUI","id":"CVE-2023-52370","kev_date_added":null,"published":"2024-02-18"},{"cvss_score":9.8,"headline":"Business logic in EMUI","id":"CVE-2023-52378","kev_date_added":null,"published":"2024-02-18"},{"cvss_score":9.8,"headline":"Code injection in EMUI","id":"CVE-2023-52381","kev_date_added":null,"published":"2024-02-18"},{"cvss_score":9.8,"headline":"Memory corruption in EMUI","id":"CVE-2023-52103","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":9.8,"headline":"Privilege escalation in EMUI","id":"CVE-2023-46773","kev_date_added":null,"published":"2023-12-06"},{"cvss_score":9.8,"headline":"Privilege escalation in EMUI","id":"CVE-2023-44105","kev_date_added":null,"published":"2023-10-11"},{"cvss_score":9.8,"headline":"Privilege escalation in EMUI","id":"CVE-2023-44106","kev_date_added":null,"published":"2023-10-11"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Huawei"]},"summary":"An arbitrary address access vulnerability in Huawei EMUI test code allows attackers to compromise service confidentiality, integrity, and availability.","url":"https://insights.sbomify.com/CVE-2021-39994/"}
