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-2026-72286 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-2026-72286/ (Markdown: https://insights.sbomify.com/CVE-2026-72286/index.md)","id":"CVE-2026-72286","markdown":"https://insights.sbomify.com/CVE-2026-72286/index.md","name":"CVE-2026-72286","record":{"aliases":["BELL-CVE-2026-72286","DEBIAN-CVE-2026-72286","GHSA-ghw4-q5h4-h5hf","UBUNTU-CVE-2026-72286"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel KVM","requires_auth":"low_privilege","summary":"Attackers could exploit incomplete SEV-SNP VM migration features to cause state inconsistencies or undefined behavior in virtualized environments.","user_interaction":"not_required","vuln_class":"other"},"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\nKVM: SEV: Do not allow intra-host migration/mirroring of SNP VMs\n\nThe intra-host migration/mirroring feature is not fully implemented for\nSEV-SNP VMs. The proper migration requires additional SNP-specific\nstate such as guest_req_mutex, guest_req_buf, and guest_resp_buf to be\ntransferred or initialized on the destination.\n\nThe SNP VM mirroring requires vmsa features to be copied as well otherwise\nASID would be bound to SNP range while VM is detected as a SEV VM.\n\nReject SNP source VMs in migration/mirroring until proper SNP state\ntransfer is implemented.\n\n[sean: let lines poke past 80 chars, tag for stable]","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: SEV: Do not allow intra-host migration/mirroring of SNP VMs","id":"CVE-2026-72286","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"KVM: nVMX: Move vTPR vs. TPR Threshold consistency check into \"normal\" checks","id":"CVE-2026-72287"},"packages":[],"prev":{"headline":"KVM: TDX: Reject concurrent change to CPUID entry count","id":"CVE-2026-72285"},"products":["Linux"],"published":"2026-08-15","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":"Attackers could exploit incomplete SEV-SNP VM migration features to cause state inconsistencies or undefined behavior in virtualized environments.","url":"https://insights.sbomify.com/CVE-2026-72286/"}
