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-2026-63072 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-2026-63072/ (Markdown: https://insights.sbomify.com/CVE-2026-63072/index.md)","id":"CVE-2026-63072","markdown":"https://insights.sbomify.com/CVE-2026-63072/index.md","name":"CVE-2026-63072","record":{"aliases":["ALPINE-CVE-2026-63072","AZL-97665","AZL-97890","AZL-97947","BELL-CVE-2026-63072","CLEANSTART-2026-VK14120","CLSA-2026-1792183929","CLSA-2026-1792496065","DEBIAN-CVE-2026-63072","ECHO-aa38-89d5-f024","GHSA-wp5f-6q39-q2f4","MINI-mcq4-94wp-pxfr","MINI-r4gh-qcfr-6phw","OESA-2026-3922","OESA-2026-3924","RHSA-2026:85249","ROOT-OS-ALPINE-315-CVE-2026-63072","ROOT-OS-ALPINE-317-CVE-2026-63072","ROOT-OS-DEBIAN-11-CVE-2026-63072","SUSE-SU-2026:4034-1","SUSE-SU-2026:4036-1","SUSE-SU-2026:4037-1","SUSE-SU-2026:4042-1","UBUNTU-CVE-2026-63072"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSSL cryptographic library","requires_auth":"none","summary":"An attacker can cause a denial of service by sending a crafted CMS message that triggers an 8-byte heap buffer overflow during decryption.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-787","name":"Out-of-bounds Write"}],"description":"Issue summary: OpenSSL CMS decryption sizes the key-unwrap output buffer based\non querying the unwrapped key size, but the AES-WRAP-PAD unwrap primitive\ncan write and cleanse more bytes than that query reports, causing an 8-byte\nout-of-bounds heap write.\n\nImpact summary: An attacker who supplies a crafted CMS message can trigger a\ndeterministic 8-byte out-of-bounds heap write when the victim decrypts it\nwith CMS_decrypt(), corrupting the heap and typically resulting in a Denial\nof Service.\n\nCWE: CWE-787: Out-of-bounds Write\n\nDescription: The key-wrap OID is potentially attacker-controlled on the wire.\nCMS unwrapping allows both id-aesNNN-wrap-pad and id-aesNNN-wrap ciphers.\nAn attacker can take a legitimate message and change a single OID byte to\nselect the padded variant while leaving the message otherwise valid. Since\nthe unwrap key is derived from the recipient's private operation (ECDH key\nagreement or ML-KEM decapsulation), the RFC 5649 integrity check cannot\npass, and the decryption fails with integrity failure.\n\nThe write is a fixed-size (8-byte), fixed-value (zero) heap overflow\nimmediately past the allocation, requires no special configuration, and is\nreachable from the public CMS_decrypt() function. The consequence is\na heap corruption leading to a Denial of Service. The fix in the CMS code\nsizes the unwrap output buffer for the worst case so a failed unwrap cannot\nwrite past the allocation.\n\nFIPS impact: no\n\nAs the CMS code lives outside the FIPS module boundary, no FIPS\nmodules are affected by this CVE.","ecosystems":["Red Hat:rhel_satellite_openvox:6::el10","Red Hat:rhel_satellite_openvox:6::el7","Red Hat:rhel_satellite_openvox:6::el8","Red
