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-2025-65493 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-2025-65493/ (Markdown: https://insights.sbomify.com/CVE-2025-65493/index.md)","id":"CVE-2025-65493","markdown":"https://insights.sbomify.com/CVE-2025-65493/index.md","name":"CVE-2025-65493","record":{"aliases":["DEBIAN-CVE-2025-65493","GHSA-x2fc-9w3j-84r4","UBUNTU-CVE-2025-65493"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libcoap CoAP library","requires_auth":"none","summary":"Remote attackers can cause denial of service in libcoap via crafted DTLS/TLS connections triggering 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 src/coap_openssl.c in OISM libcoap 4.3.5 allows remote attackers to cause a denial of service via a crafted DTLS/TLS connection that triggers BIO_get_data() 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-2025-65493","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":"Null dereference in n/a","id":"CVE-2025-65494"},"packages":[],"prev":{"headline":"XDocReport affected by an XML External Entity (XXE) vulnerability","id":"CVE-2025-65482"},"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-2025-65494","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 denial of service in libcoap via crafted DTLS/TLS connections triggering a NULL pointer dereference.","url":"https://insights.sbomify.com/CVE-2025-65493/"}
