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-2025-11936/ (Markdown: https://insights.sbomify.com/CVE-2025-11936/index.md)","id":"CVE-2025-11936","markdown":"https://insights.sbomify.com/CVE-2025-11936/index.md","name":"CVE-2025-11936","record":{"aliases":["DEBIAN-CVE-2025-11936","GHSA-2mmq-prpj-ww9q","UBUNTU-CVE-2025-11936"],"analysis":null,"analysis_generated_by":null,"assigner":"wolfSSL","cpe":[{"product":"wolfssl","vendor":"wolfssl"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation in the TLS 1.3 KeyShareEntry parsing in wolfSSL v5.8.2 on multiple platforms allows a remote unauthenticated attacker to cause a denial-of-service by sending a crafted ClientHello message containing duplicate KeyShareEntry values for the same supported group, leading to excessive CPU and memory consumption during ClientHello processing.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Potential DoS Vulnerability through Multiple KeyShareEntry with Same Group in TLS 1.3 ClientHello","id":"CVE-2025-11936","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wolfssl:wolfssl","products":["wolfssl:wolfssl"],"type":null,"year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Stored XSS through a system message in SecurePoll","id":"CVE-2025-11937"},"packages":[],"prev":{"headline":"Forward Secrecy Violation in WolfSSL TLS 1.3","id":"CVE-2025-11935"},"products":["wolfSSL"],"published":"2025-11-21","related":[{"cvss_score":10,"headline":"Buffer overread in domain name matching","id":"CVE-2024-5991","kev_date_added":null,"published":"2024-08-27"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2021-37155","kev_date_added":null,"published":"2021-07-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-36177","kev_date_added":null,"published":"2021-01-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-2896","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-2897","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2014-2898","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-16748","kev_date_added":null,"published":"2019-09-24"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-08","vendors":["wolfSSL"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2025-11936/"}
