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-2021-37045 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-2021-37045/ (Markdown: https://insights.sbomify.com/CVE-2021-37045/index.md)","id":"CVE-2021-37045","markdown":"https://insights.sbomify.com/CVE-2021-37045/index.md","name":"CVE-2021-37045","record":{"aliases":["GHSA-7gx6-8phm-v624"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Huawei mobile OS","requires_auth":"none","summary":"A use-after-free flaw in Huawei mobile operating systems allows attackers to execute kernel-mode code or cause unexpected device restarts.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"emui","vendor":"huawei"},{"product":"harmonyos","vendor":"huawei"},{"product":"magic_ui","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":[{"id":"CWE-416","name":"Use After Free"}],"description":"There is an UAF vulnerability in Huawei Smartphone.Successful exploitation of this vulnerability may cause the device to restart unexpectedly and the kernel-mode code to be executed.","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":"Use after free in EMUI","id":"CVE-2021-37045","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"huawei:emui","products":["huawei:emui","huawei:harmonyos","huawei:magic_ui"],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in EMUI","id":"CVE-2021-37046"},"packages":[],"prev":{"headline":"Missing authorization in EMUI","id":"CVE-2021-37044"},"products":["EMUI","HarmonyOS","Magic UI"],"published":"2021-12-08","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":"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":"2024-08-04","vendors":["Huawei"]},"summary":"A use-after-free flaw in Huawei mobile operating systems allows attackers to execute kernel-mode code or cause unexpected device restarts.","url":"https://insights.sbomify.com/CVE-2021-37045/"}
