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-2026-42764 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-2026-42764/ (Markdown: https://insights.sbomify.com/CVE-2026-42764/index.md)","id":"CVE-2026-42764","markdown":"https://insights.sbomify.com/CVE-2026-42764/index.md","name":"CVE-2026-42764","record":{"aliases":["ALPINE-CVE-2026-42764","BELL-CVE-2026-42764","DEBIAN-CVE-2026-42764","GHSA-5pg7-f6xv-j6m4","JLSEC-2026-1137","MINI-pp4h-f74w-w939","UBUNTU-CVE-2026-42764"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenSSL QUIC server","requires_auth":"none","summary":"Attackers can crash the OpenSSL QUIC server by sending invalid initial packets when address validation is disabled, 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":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":"Issue summary: Receiving a QUIC initial packet with an invalid token may\ntrigger a NULL pointer dereference in the OpenSSL QUIC server with\naddress validation disabled.\n\nImpact summary: NULL pointer dereference typically causes abnormal termination\nof the affected QUIC server process and a Denial of Service.\n\nIf the address validation is disabled in the OpenSSL QUIC server\nimplementation, an attacker can crash the server by sending an initial\npacket with an invalid or expired token.\n\nBy default, the client address validation is enabled in the OpenSSL QUIC server\nimplementation, which makes the default configuration not vulnerable\nto this issue.
