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-2025-40080 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-2025-40080/ (Markdown: https://insights.sbomify.com/CVE-2025-40080/index.md)","id":"CVE-2025-40080","markdown":"https://insights.sbomify.com/CVE-2025-40080/index.md","name":"CVE-2025-40080","record":{"aliases":["AZL-68879","BELL-CVE-2025-40080","DEBIAN-CVE-2025-40080","GHSA-mp9c-x94p-8jh7","ROOT-OS-DEBIAN-11-CVE-2025-40080","ROOT-OS-DEBIAN-12-CVE-2025-40080","ROOT-OS-DEBIAN-13-CVE-2025-40080","ROOT-OS-UBUNTU-2204-CVE-2025-40080","ROOT-OS-UBUNTU-2404-CVE-2025-40080","UBUNTU-CVE-2025-40080"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel NBD","requires_auth":"low_privilege","summary":"The Linux kernel NBD module allowed unsupported socket types, potentially causing denial of service; attackers with local access could exploit this.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnbd: restrict sockets to TCP and UDP\n\nRecently, syzbot started to abuse NBD with all kinds of sockets.\n\nCommit cf1b2326b734 (\"nbd: verify socket is supported during setup\")\nmade sure the socket supported a shutdown() method.\n\nExplicitely accept TCP and UNIX stream sockets.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"nbd: restrict sockets to TCP and UDP","id":"CVE-2025-40080","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"perf: arm_spe: Prevent overflow in PERF_IDX2OFF()","id":"CVE-2025-40081"},"packages":[],"prev":{"headline":"riscv, bpf: Sign extend struct ops return values properly","id":"CVE-2025-40079"},"products":["Linux"],"published":"2025-10-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"The Linux kernel NBD module allowed unsupported socket types, potentially causing denial of service; attackers with local access could exploit this.","url":"https://insights.sbomify.com/CVE-2025-40080/"}
