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-2026-72285 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-2026-72285/ (Markdown: https://insights.sbomify.com/CVE-2026-72285/index.md)","id":"CVE-2026-72285","markdown":"https://insights.sbomify.com/CVE-2026-72285/index.md","name":"CVE-2026-72285","record":{"aliases":["DEBIAN-CVE-2026-72285","GHSA-725c-hm4j-27fv","UBUNTU-CVE-2026-72285"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel KVM","requires_auth":"low_privilege","summary":"A race condition in Linux KVM TDX allows attackers to trigger out-of-bounds memory access, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: TDX: Reject concurrent change to CPUID entry count\n\nReject KVM_TDX_INIT_VM if userspace changes cpuid.nent between the\ninitial read and the subsequent copy of the initialization data.\n\ntdx_td_init() first reads user_data-\u003ecpuid.nent to size the flexible\nkvm_tdx_init_vm copy.
