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-2026-98282 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-2026-98282/ (Markdown: https://insights.sbomify.com/CVE-2026-98282/index.md)","id":"CVE-2026-98282","markdown":"https://insights.sbomify.com/CVE-2026-98282/index.md","name":"CVE-2026-98282","record":{"aliases":["AZL-106383","BELL-CVE-2026-98282","DEBIAN-CVE-2026-98282","GHSA-8m3g-gm8v-p3m6","UBUNTU-CVE-2026-98282"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An integer overflow in the Linux kernel's PowerPC IOMMU code allows attackers to bypass bounds checks, potentially leading to privilege escalation or code execution.","user_interaction":"not_required","vuln_class":"integer_overflow"},"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\npowerpc/iommu: Fix the overflow validation in iommu_tce_check_ioba\n\nThe commit b1af23d836f8 (\"KVM: PPC: iommu: Unify TCE checking\") unified\nIOBA parameter checking across KVM and VFIO into iommu_tce_check_ioba().\nWhile doing so, the passed in argument npages is ignored and constant\nvalue '1' is used leaving out a possible overflow as the callers can\nlegitimately be using npages \u003e 1 for H_STUFF_TCE or H_PUT_TCE_INDIRECT\ncases.\n\nFix this by accounting for 'npages', checking for arithmetic overflow,\nand verifying that the entire requested range (ioba - offset + npages)\ndoes not exceed the table capacity 'size'.","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":"powerpc/iommu: Fix the overflow validation in iommu_tce_check_ioba","id":"CVE-2026-98282","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"KVM: PPC: Book3S HV: fix use-after-free in kvmhv_emulate_tlbie_all_lpid()","id":"CVE-2026-98283"},"packages":[],"prev":{"headline":"futex: Also allocate private hash on vfork()","id":"CVE-2026-98281"},"products":["Linux"],"published":"2026-10-06","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"An integer overflow in the Linux kernel's PowerPC IOMMU code allows attackers to bypass bounds checks, potentially leading to privilege escalation or code execution.","url":"https://insights.sbomify.com/CVE-2026-98282/"}
