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-2016-6490 in the wild and no public exploit code.\n\nAffected product: Qemu Qemu. 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-2016-6490/ (Markdown: https://insights.sbomify.com/CVE-2016-6490/index.md)","id":"CVE-2016-6490","markdown":"https://insights.sbomify.com/CVE-2016-6490/index.md","name":"CVE-2016-6490","record":{"aliases":["DEBIAN-CVE-2016-6490","GHSA-683h-m32r-vcgg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"QEMU virtualization","requires_auth":"high_privilege","summary":"Local guest administrators can crash the QEMU process via an infinite loop triggered by a zero-length descriptor buffer in virtio.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"qemu","vendor":"qemu"}],"cvss":{"score":4.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"The virtqueue_map_desc function in hw/virtio/virtio.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via a zero length for the descriptor buffer.","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":"Denial of service in n/a","id":"CVE-2016-6490","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"qemu:qemu","products":["qemu:qemu"],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2016-6491"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2016-6489"},"products":["n/a"],"published":"2016-12-10","related":[{"cvss_score":10,"headline":"Null dereference in n/a","id":"CVE-2022-36648","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":10,"headline":"Race condition in n/a","id":"CVE-2015-8556","kev_date_added":null,"published":"2017-03-24"},{"cvss_score":9.9,"headline":"Use after free in n/a","id":"CVE-2009-3616","kev_date_added":null,"published":"2009-10-23"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12928","kev_date_added":null,"published":"2019-06-24"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2019-12929","kev_date_added":null,"published":"2019-06-24"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-20815","kev_date_added":null,"published":"2019-05-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-8380","kev_date_added":null,"published":"2017-08-28"}],"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":"Local guest administrators can crash the QEMU process via an infinite loop triggered by a zero-length descriptor buffer in virtio.","url":"https://insights.sbomify.com/CVE-2016-6490/"}
