Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-36052 in the wild and no public exploit code.\n\nAffected product: contiki-ng. 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-2022-36052/ (Markdown: https://insights.sbomify.com/CVE-2022-36052/index.md)","id":"CVE-2022-36052","markdown":"https://insights.sbomify.com/CVE-2022-36052/index.md","name":"CVE-2022-36052","record":{"aliases":["GHSA-vwr8-6mqv-x7f5"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IoT operating system","requires_auth":"low_privilege","summary":"An out-of-bounds read in Contiki-NG's 6LoWPAN UDP header processing allows attackers to cause crashes or leak memory via crafted packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"contiki-ng","vendor":"contiki-ng"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices. The 6LoWPAN implementation in Contiki-NG may cast a UDP header structure at a certain offset in a packet buffer. The code does not check whether the packet buffer is large enough to fit a full UDP header structure from the offset where the casting is made. Hence, it is possible to cause an out-of-bounds read beyond the packet buffer. The problem affects anyone running devices with Contiki-NG versions previous to 4.8, and which may receive 6LoWPAN packets from external parties. The problem has been patched in Contiki-NG version 4.8.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Out-of-bounds read when decompressing UDP header","id":"CVE-2022-36052","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Out-of-bounds read in the uIP buffer module","id":"CVE-2022-36053"},"packages":[],"prev":{"headline":"Broken Authorization in ZITADEL Actions","id":"CVE-2022-36051"},"products":["contiki-ng"],"published":"2022-09-01","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2018-19417","kev_date_added":null,"published":"2018-11-21"},{"cvss_score":9.8,"headline":"Contiki-NG has off-by-one error in Antelope DBMS","id":"CVE-2023-30546","kev_date_added":null,"published":"2023-04-26"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-24336","kev_date_added":null,"published":"2020-12-11"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14934","kev_date_added":null,"published":"2020-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14935","kev_date_added":null,"published":"2020-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14936","kev_date_added":null,"published":"2020-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-8359","kev_date_added":null,"published":"2020-04-23"}],"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":"2025-04-23","vendors":["contiki-ng"]},"summary":"An out-of-bounds read in Contiki-NG's 6LoWPAN UDP header processing allows attackers to cause crashes or leak memory via crafted packets.","url":"https://insights.sbomify.com/CVE-2022-36052/"}
