It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-68451 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-68451/ (Markdown: https://insights.sbomify.com/CVE-2026-68451/index.md)","id":"CVE-2026-68451","markdown":"https://insights.sbomify.com/CVE-2026-68451/index.md","name":"CVE-2026-68451","record":{"aliases":["BELL-CVE-2026-68451","DEBIAN-CVE-2026-68451","GHSA-4fv3-cqpg-5v3h","UBUNTU-CVE-2026-68451"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A missing length validation in the Linux kernel s390/zcrypt driver allows attackers to trigger a buffer overflow via crafted CCA ECC private key requests.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ns390/zcrypt: Validate length for CCA ECC private key requests\n\ncca_ecc2protkey() derives the copy length for the CPRB parameter\nblock directly from the length field in the key token.
