It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-24921 in the wild and no public exploit code.\n\nAffected product: Huawei Harmonyos. 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-2026-24921/ (Markdown: https://insights.sbomify.com/CVE-2026-24921/index.md)","id":"CVE-2026-24921","markdown":"https://insights.sbomify.com/CVE-2026-24921/index.md","name":"CVE-2026-24921","record":{"aliases":["GHSA-pqx7-gr66-v8pw"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HarmonyOS HDC module","requires_auth":"high_privilege","summary":"An address read vulnerability in the HarmonyOS HDC module allows attackers to compromise confidentiality and availability.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"harmonyos","vendor":"huawei"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Address read vulnerability in the HDC module.\nImpact: Successful exploitation of this vulnerability will affect availability and confidentiality.","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":"Information disclosure in HarmonyOS","id":"CVE-2026-24921","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"huawei:harmonyos","products":["huawei:harmonyos"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in HarmonyOS","id":"CVE-2026-24922"},"packages":[],"prev":{"headline":"Missing authorization in EMUI","id":"CVE-2026-24920"},"products":["HarmonyOS"],"published":"2026-02-06","related":[{"cvss_score":10,"headline":"Memory corruption in HarmonyOS","id":"CVE-2026-34865","kev_date_added":null,"published":"2026-04-13"},{"cvss_score":10,"headline":"Other in HarmonyOS","id":"CVE-2023-34157","kev_date_added":null,"published":"2023-06-16"},{"cvss_score":9.8,"headline":"Denial of service in HarmonyOS","id":"CVE-2023-41294","kev_date_added":null,"published":"2023-09-25"},{"cvss_score":9.8,"headline":"Denial of service in HarmonyOS","id":"CVE-2022-48478","kev_date_added":null,"published":"2023-05-26"},{"cvss_score":9.8,"headline":"Memory corruption in HarmonyOS","id":"CVE-2022-48479","kev_date_added":null,"published":"2023-05-26"},{"cvss_score":9.8,"headline":"Race condition in HarmonyOS","id":"CVE-2022-46316","kev_date_added":null,"published":"2022-12-20"},{"cvss_score":9.8,"headline":"Memory corruption in HarmonyOS","id":"CVE-2022-38980","kev_date_added":null,"published":"2022-10-14"}],"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":"2026-02-06","vendors":["Huawei"]},"summary":"An address read vulnerability in the HarmonyOS HDC module allows attackers to compromise confidentiality and availability.","url":"https://insights.sbomify.com/CVE-2026-24921/"}
