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-2011-2512 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2011-2512/ (Markdown: https://insights.sbomify.com/CVE-2011-2512/index.md)","id":"CVE-2011-2512","markdown":"https://insights.sbomify.com/CVE-2011-2512/index.md","name":"CVE-2011-2512","record":{"aliases":["DSA-2270-1","GHSA-g293-9rv5-w2qx"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"KVM virtualization","requires_auth":"low_privilege","summary":"Guest users can trigger a crash or execute arbitrary code on the host by sending a negative virtqueue number, bypassing validation checks.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"qemu-kvm","vendor":"kvm_group"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"AV:A/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The virtio_queue_notify in qemu-kvm 0.14.0 and earlier does not properly validate the virtqueue number, which allows guest users to cause a denial of service (guest crash) and possibly execute arbitrary code via a negative number in the Queue Notify field of the Virtio Header, which bypasses a signed comparison.","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":"Integer overflow in n/a","id":"CVE-2011-2512","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2011"},"n_packages":0,"n_references":14,"next":{"headline":"Information disclosure in n/a","id":"CVE-2011-2513"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2011-2511"},"products":["n/a"],"published":"2012-06-21","related":[{"cvss_score":7.4,"headline":"Memory corruption in n/a","id":"CVE-2012-0029","kev_date_added":null,"published":"2012-01-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Guest users can trigger a crash or execute arbitrary code on the host by sending a negative virtqueue number, bypassing validation checks.","url":"https://insights.sbomify.com/CVE-2011-2512/"}
