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-2026-80547 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-2026-80547/ (Markdown: https://insights.sbomify.com/CVE-2026-80547/index.md)","id":"CVE-2026-80547","markdown":"https://insights.sbomify.com/CVE-2026-80547/index.md","name":"CVE-2026-80547","record":{"aliases":["AZL-97737","BELL-CVE-2026-80547","DEBIAN-CVE-2026-80547","GHSA-9vqh-hxm7-9fwm","UBUNTU-CVE-2026-80547"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A missing lock in the s390 vfio_ccw driver allows race conditions on asynchronous hardware events, potentially causing system instability or denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/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: Implement a crw lock\n\nUnlike the channel_program struct, which covers synchronous I/O\nsubmissions and asynchronous interrupts, the CRW region relies\nexclusively on asynchronous events coming from hardware.\n\nImplement a lock to manage the list of those payloads, to ensure\nthey are read cohesively.","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: Implement a crw lock","id":"CVE-2026-80547","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"s390/vfio_ccw: Selectively expand io_mutex","id":"CVE-2026-80548"},"packages":[],"prev":{"headline":"s390/zcrypt: Improve CCA CPRB length and overflow checks","id":"CVE-2026-80546"},"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 missing lock in the s390 vfio_ccw driver allows race conditions on asynchronous hardware events, potentially causing system instability or denial of service.","url":"https://insights.sbomify.com/CVE-2026-80547/"}
