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-2026-98716 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-2026-98716/ (Markdown: https://insights.sbomify.com/CVE-2026-98716/index.md)","id":"CVE-2026-98716","markdown":"https://insights.sbomify.com/CVE-2026-98716/index.md","name":"CVE-2026-98716","record":{"aliases":["AZL-109439","BELL-CVE-2026-98716","DEBIAN-CVE-2026-98716","GHSA-hpgm-5w85-35mm","UBUNTU-CVE-2026-98716"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel KVM","requires_auth":"low_privilege","summary":"A flaw in Linux KVM SVM allows bypassing MSR interception checks, potentially enabling guest-to-host security bypasses.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"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\nKVM: SVM: Use the active VMCB's MSR bitmap when checking if MSR is intercepted\n\nUse the MSR permission bitmap of the active VMCB instead of assuming that\nKVM is always using vmcb02's bitmap when L2 is active, as KVM uses msrpm02\nif and only if L1 wants to intercept MSR accesses, i.e. if and only if KVM\nneeds to merge msprm01 with msrpm12.\n\nDon't bother tracking the virtual address of the bitmap that's being used,\nas __va() is cheap on x86, and caching the virtual address would introduce\nyet another source of potentially stale information.","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: SVM: Use the active VMCB's MSR bitmap when checking if MSR is intercepted","id":"CVE-2026-98716","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"KVM: x86/mmu: Bail from shadow walks if the root is invalid or a dummy","id":"CVE-2026-98717"},"packages":[],"prev":{"headline":"KVM: SVM: Preserve TLB control (i.e. pending TLB flush) on failed VMRUN","id":"CVE-2026-98715"},"products":["Linux"],"published":"2026-10-18","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":"2026-10-21","vendors":["Linux"]},"summary":"A flaw in Linux KVM SVM allows bypassing MSR interception checks, potentially enabling guest-to-host security bypasses.","url":"https://insights.sbomify.com/CVE-2026-98716/"}
