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-2021-22332 in the wild and no public exploit code.\n\nAffected product: CloudEngine 12800;CloudEngine 5800;CloudEngine 6800;CloudEngine 7800. 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-2021-22332/ (Markdown: https://insights.sbomify.com/CVE-2021-22332/index.md)","id":"CVE-2021-22332","markdown":"https://insights.sbomify.com/CVE-2021-22332/index.md","name":"CVE-2021-22332","record":{"aliases":["GHSA-g9cv-62xc-fj2v"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CloudEngine switch","requires_auth":"none","summary":"Attackers can cause a module crash and service disruption on Huawei CloudEngine switches by exploiting a pointer double free vulnerability.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"cloudengine_12800_firmware","vendor":"huawei"},{"product":"cloudengine_5800_firmware","vendor":"huawei"},{"product":"cloudengine_6800_firmware","vendor":"huawei"},{"product":"cloudengine_7800_firmware","vendor":"huawei"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"There is a pointer double free vulnerability in some versions of CloudEngine 5800, CloudEngine 6800, CloudEngine 7800 and CloudEngine 12800.
