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-2025-65494 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-2025-65494/ (Markdown: https://insights.sbomify.com/CVE-2025-65494/index.md)","id":"CVE-2025-65494","markdown":"https://insights.sbomify.com/CVE-2025-65494/index.md","name":"CVE-2025-65494","record":{"aliases":["DEBIAN-CVE-2025-65494","GHSA-vm7h-x472-77pq","UBUNTU-CVE-2025-65494"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CoAP library","requires_auth":"none","summary":"Remote attackers can cause a denial of service in libcoap by sending a crafted X.509 certificate that triggers a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libcoap","vendor":"libcoap"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-476","name":"NULL Pointer Dereference"}],"description":"NULL pointer dereference in get_san_or_cn_from_cert() in src/coap_openssl.c in OISM libcoap 4.3.5 allows remote attackers to cause a denial of service via a crafted X.509 certificate that causes sk_GENERAL_NAME_value() to return NULL.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Null dereference in n/a","id":"CVE-2025-65494","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Integer overflow in n/a","id":"CVE-2025-65495"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2025-65493"},"products":["n/a"],"published":"2025-11-24","related":[{"cvss_score":8.8,"headline":"libcoap Out-of-Bounds Read in OSCORE CBOR Unwrap Handling","id":"CVE-2026-29013","kev_date_added":null,"published":"2026-04-17"},{"cvss_score":8.2,"headline":"libcoap Stack-Based Buffer Overflow in Address Resolution DoS or Potential RCE","id":"CVE-2025-34468","kev_date_added":null,"published":"2025-12-31"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2025-65493","kev_date_added":null,"published":"2025-11-24"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2025-65495","kev_date_added":null,"published":"2025-11-24"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2023-30362","kev_date_added":null,"published":"2023-06-23"},{"cvss_score":6.5,"headline":"Information disclosure in n/a","id":"CVE-2025-59391","kev_date_added":null,"published":"2025-12-08"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-24","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service in libcoap by sending a crafted X.509 certificate that triggers a null pointer dereference.","url":"https://insights.sbomify.com/CVE-2025-65494/"}
