An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-22327 in the wild and no public exploit code.\n\nAffected product: HUAWEI P30. 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-2021-22327/ (Markdown: https://insights.sbomify.com/CVE-2021-22327/index.md)","id":"CVE-2021-22327","markdown":"https://insights.sbomify.com/CVE-2021-22327/index.md","name":"CVE-2021-22327","record":{"aliases":["GHSA-h5qw-wfpg-g2wr"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Huawei smartphone","requires_auth":"none","summary":"An arbitrary memory write vulnerability in Huawei smartphones allows attackers to cause service abnormalities via malicious file parsing.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"p30_firmware","vendor":"huawei"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"There is an arbitrary memory write vulnerability in Huawei smart phone when processing file parsing.
