An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-46896 exists.\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-2021-46896/ (Markdown: https://insights.sbomify.com/CVE-2021-46896/index.md)","id":"CVE-2021-46896","markdown":"https://insights.sbomify.com/CVE-2021-46896/index.md","name":"CVE-2021-46896","record":{"aliases":["GHSA-82h7-455m-f9mp"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PX4 Autopilot","requires_auth":"none","summary":"A buffer overflow in PX4-Autopilot allows attackers to cause a denial of service via a specific message handler.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"px4_drone_autopilot","vendor":"dronecode"}],"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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer Overflow vulnerability in PX4-Autopilot allows attackers to cause a denial of service via handler function handling msgid 332.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2021-46896","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Wagtail CRX CodeRed Extensions vulnerable to Path Traversal","id":"CVE-2021-46897"},"packages":[],"prev":{"headline":"Security feature bypass in EMUI","id":"CVE-2021-46895"},"products":["n/a"],"published":"2023-07-06","related":[{"cvss_score":8.1,"headline":"Business logic in n/a","id":"CVE-2026-26741","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":8.1,"headline":"Security feature bypass in n/a","id":"CVE-2026-26742","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":7.9,"headline":"Memory corruption in n/a","id":"CVE-2024-40427","kev_date_added":null,"published":"2025-01-07"},{"cvss_score":7.8,"headline":"Zenoh uORB Subscriber Allows Arbitrary Stack Allocation (PX4/PX4-Autopilot)","id":"CVE-2026-32708","kev_date_added":null,"published":"2026-03-13"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2024-38952","kev_date_added":null,"published":"2024-06-25"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2021-34125","kev_date_added":null,"published":"2023-03-09"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-20","vendors":["n/a"]},"summary":"A buffer overflow in PX4-Autopilot allows attackers to cause a denial of service via a specific message handler.","url":"https://insights.sbomify.com/CVE-2021-46896/"}
