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-2026-37539 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-2026-37539/ (Markdown: https://insights.sbomify.com/CVE-2026-37539/index.md)","id":"CVE-2026-37539","markdown":"https://insights.sbomify.com/CVE-2026-37539/index.md","name":"CVE-2026-37539","record":{"aliases":["GHSA-9j4x-6r48-xgv9"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CAN bus library","requires_auth":"none","summary":"Remote attackers can cause denial of service or execute arbitrary code via crafted CAN FD frames in the cannelloni library.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AC:L/AV:N/A:H/C:H/I:H/PR:N/S:U/UI:N","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Buffer overflow vulnerability in cannelloni v2.0.0 in CAN frame parsing in parser.cpp in function parseCANFrame, and decoder.cpp in function decodeFrame allowing remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted CAN FD frames.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2026-37539","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Integer overflow in n/a","id":"CVE-2026-37540"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2026-37538"},"products":["n/a"],"published":"2026-05-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-01","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service or execute arbitrary code via crafted CAN FD frames in the cannelloni library.","url":"https://insights.sbomify.com/CVE-2026-37539/"}
