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-2026-80551 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-2026-80551/ (Markdown: https://insights.sbomify.com/CVE-2026-80551/index.md)","id":"CVE-2026-80551","markdown":"https://insights.sbomify.com/CVE-2026-80551/index.md","name":"CVE-2026-80551","record":{"aliases":["AZL-97824","BELL-CVE-2026-80551","DEBIAN-CVE-2026-80551","GHSA-p29x-7599-2m4p","UBUNTU-CVE-2026-80551"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A race condition in the s390 vfio_ccw driver allows attackers to manipulate IDAW addresses, potentially leading to memory corruption or privilege escalation.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ns390/vfio_ccw: Ensure first IDAW remains constant\n\nThe first IDAW in a list does not need to be on a 2K/4K boundary\nlike all others, and so is read separately to accurately calculate\nthe size of the buffer needed to read the full IDAL.\n\nVerify that the address found in the first IDAW is unchanged between\nreads, to ensure a consistent set of IDAWs being worked with.","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":"s390/vfio_ccw: Ensure first IDAW remains constant","id":"CVE-2026-80551","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"s390/vfio_ccw: Ensure index for read/write regions are within range","id":"CVE-2026-80552"},"packages":[],"prev":{"headline":"s390/vfio_ccw: Fix out of bounds check on CCW array","id":"CVE-2026-80550"},"products":["Linux"],"published":"2026-08-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"A race condition in the s390 vfio_ccw driver allows attackers to manipulate IDAW addresses, potentially leading to memory corruption or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-80551/"}
