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-2026-42767 in the wild and no public exploit code.\n\nAffected product: Openssl Openssl. 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-2026-42767/ (Markdown: https://insights.sbomify.com/CVE-2026-42767/index.md)","id":"CVE-2026-42767","markdown":"https://insights.sbomify.com/CVE-2026-42767/index.md","name":"CVE-2026-42767","record":{"aliases":["ALPINE-CVE-2026-42767","AZL-89787","AZL-89870","AZL-89922","BELL-CVE-2026-42767","CLSA-2026-1782983109","DEBIAN-CVE-2026-42767","ECHO-86de-f803-ef79","GHSA-gxhg-7jx8-m22j","JLSEC-2026-1139","MINI-74p3-fj72-g9x2","MINI-c2qm-45cv-hv74","SUSE-SU-2026:22437-1","SUSE-SU-2026:22449-1","SUSE-SU-2026:3004-1","UBUNTU-CVE-2026-42767"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSSL library","requires_auth":"none","summary":"A malicious CMP server can crash OpenSSL CMP clients via a crafted response, causing denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"openssl","vendor":"openssl"}],"cvss":{"score":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Issue summary: An attacker-controlled CMP (Certificate Management Protocol)\nserver could trigger a NULL pointer dereference in a CMP client application.\n\nImpact summary: A NULL pointer dereference causes a crash of the\napplication and a Denial of Service.\n\nAn attacker controlling a CMP server (or acting as a man-in-the-middle) could\ncraft a CMP response containing a CRMF (Certificate Request Message Format)\nCertRepMessage with an EncryptedValue structure where the symmAlg field\nhas an algorithm OID but no parameters field.
