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-2026-68454 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-2026-68454/ (Markdown: https://insights.sbomify.com/CVE-2026-68454/index.md)","id":"CVE-2026-68454","markdown":"https://insights.sbomify.com/CVE-2026-68454/index.md","name":"CVE-2026-68454","record":{"aliases":["BELL-CVE-2026-68454","DEBIAN-CVE-2026-68454","GHSA-4h5w-742q-hw8j","UBUNTU-CVE-2026-68454"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel KVM","requires_auth":"low_privilege","summary":"A null pointer dereference in KVM s390 PCI handling allows a guest to cause a kernel crash by registering IRQs without a summary bit.","user_interaction":"not_required","vuln_class":"null_dereference"},"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":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: s390: pci: Fix handling of AIF enable without AISB\n\nWhen a guest seeks to register IRQs without a summary bit specified,\nensure that the associated GAITE then stores 0 for the guest AISB\nlocation instead of virt_to_phys(page_address(NULL)).","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":"KVM: s390: pci: Fix handling of AIF enable without AISB","id":"CVE-2026-68454","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"liveupdate: validate session type before performing operation","id":"CVE-2026-68455"},"packages":[],"prev":{"headline":"s390/zcrypt: Fix buffer over-read in cca_cipher2protkey","id":"CVE-2026-68453"},"products":["Linux"],"published":"2026-08-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A null pointer dereference in KVM s390 PCI handling allows a guest to cause a kernel crash by registering IRQs without a summary bit.","url":"https://insights.sbomify.com/CVE-2026-68454/"}
