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-2016-7422 in the wild and no public exploit code.\n\nAffected product: Opensuse Leap. 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-2016-7422/ (Markdown: https://insights.sbomify.com/CVE-2016-7422/index.md)","id":"CVE-2016-7422","markdown":"https://insights.sbomify.com/CVE-2016-7422/index.md","name":"CVE-2016-7422","record":{"aliases":["DEBIAN-CVE-2016-7422","GHSA-fp4p-m87h-5fx8"],"analysis":{"component_type":"operating_system","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 OS administrators can crash the QEMU process via a NULL pointer dereference in virtqueue_map_desc, causing denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"leap","vendor":"opensuse"},{"product":"qemu","vendor":"qemu"},{"product":"openstack","vendor":"redhat"},{"product":"virtualization","vendor":"redhat"}],"cvss":{"score":6,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/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 (NULL pointer dereference and QEMU process crash) via a large I/O descriptor buffer length value.","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":"Null dereference in n/a","id":"CVE-2016-7422","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"opensuse:leap","products":["opensuse:leap","qemu:qemu","redhat:openstack","redhat:virtualization"],"type":"null_dereference","year":"2016"},"n_packages":0,"n_references":9,"next":{"headline":"Memory corruption in n/a","id":"CVE-2016-7423"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2016-7421"},"products":["n/a"],"published":"2016-12-10","related":[{"cvss_score":5.3,"headline":"Oracle Java SE Integrity Check","id":"CVE-2015-4902","kev_date_added":"2022-03-03","published":"2015-10-21"},{"cvss_score":9.9,"headline":"package builds could use directory traversal to write outside of target area","id":"CVE-2017-14804","kev_date_added":null,"published":"2018-03-01"},{"cvss_score":9.8,"headline":"Teeworlds before 0.7.4 has an integer overflow when computing a tilemap size.","id":"CVE-2019-20787","kev_date_added":null,"published":"2020-04-22"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2019-8341","kev_date_added":null,"published":"2019-02-15"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2019-6438","kev_date_added":null,"published":"2019-01-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-18215","kev_date_added":null,"published":"2018-03-05"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-6542","kev_date_added":null,"published":"2017-03-27"}],"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":"Local guest OS administrators can crash the QEMU process via a NULL pointer dereference in virtqueue_map_desc, causing denial of service.","url":"https://insights.sbomify.com/CVE-2016-7422/"}
