It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-35465 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-35465/ (Markdown: https://insights.sbomify.com/CVE-2021-35465/index.md)","id":"CVE-2021-35465","markdown":"https://insights.sbomify.com/CVE-2021-35465/index.md","name":"CVE-2021-35465","record":{"aliases":["GHSA-2g78-x942-h8vj"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Arm Cortex-M processors","requires_auth":"high_privilege","summary":"A flaw in Arm Cortex-M processors allows a non-secure handler to read or write secure context memory due to improper exception handling in VLLDM instructions.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"china_star-mc1_firmware","vendor":"arm"},{"product":"cortex-m33_firmware","vendor":"arm"},{"product":"cortex-m35p_firmware","vendor":"arm"},{"product":"cortex-m55_firmware","vendor":"arm"}],"cvss":{"score":3.4,"severity":"low","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"Certain Arm products before 2021-08-23 do not properly consider the effect of exceptions on a VLLDM instruction.
