It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-2962 exists.\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-2022-2962/ (Markdown: https://insights.sbomify.com/CVE-2022-2962/index.md)","id":"CVE-2022-2962","markdown":"https://insights.sbomify.com/CVE-2022-2962/index.md","name":"CVE-2022-2962","record":{"aliases":["AZL-10975","AZL-35159","DEBIAN-CVE-2022-2962","GHSA-wmwv-5vwp-c54w","openSUSE-SU-2024:12393-1"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"QEMU emulator","requires_auth":"low_privilege","summary":"A malicious guest can crash the QEMU host process via a DMA reentrancy flaw in Tulip device emulation, causing denial of service.","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":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-662","name":"Improper Synchronization"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.","ecosystems":["openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in QEMU","id":"CVE-2022-2962","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"qemu:qemu","products":["qemu:qemu"],"type":"denial_of_service","year":"2022"},"n_packages":1,"n_references":2,"next":{"headline":"Denial of service in jasper","id":"CVE-2022-2963"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["7.1.0-2.1"],"introduced":["0"],"last_affected":[],"package":"qemu","purl":"pkg:rpm/opensuse/qemu\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:12393-1"}],"prev":{"headline":"Use after free in Kernel","id":"CVE-2022-2961"},"products":["QEMU"],"published":"2022-09-13","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":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-23","vendors":["n/a"]},"summary":"A malicious guest can crash the QEMU host process via a DMA reentrancy flaw in Tulip device emulation, causing denial of service.","url":"https://insights.sbomify.com/CVE-2022-2962/"}
