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-2025-12464 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2025-12464/ (Markdown: https://insights.sbomify.com/CVE-2025-12464/index.md)","id":"CVE-2025-12464","markdown":"https://insights.sbomify.com/CVE-2025-12464/index.md","name":"CVE-2025-12464","record":{"aliases":["AZL-69631","BELL-CVE-2025-12464","DEBIAN-CVE-2025-12464","GHSA-59fq-gggw-pqjr","UBUNTU-CVE-2025-12464"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"QEMU e1000 device","requires_auth":"none","summary":"A malicious guest user can crash the QEMU host process via a stack buffer overflow in the e1000 network device loopback mode.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A stack-based buffer overflow was found in the QEMU e1000 network device. The code for padding short frames was dropped from individual network devices and moved to the net core code. The issue stems from the device's receive code still being able to process a short frame in loopback mode. This could lead to a buffer overrun in the e1000_receive_iov() function via the loopback code path. A malicious guest user could use this vulnerability to crash the QEMU process on the host, resulting in a denial of service.","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":"Qemu-kvm: stack buffer overflow in e1000 device via short frames in loopback mode","id":"CVE-2025-12464","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Blind SQL Injection in QuickCMS","id":"CVE-2025-12465"},"packages":[],"prev":{"headline":"Unauthenticated SQL Injection in Guetebruck G-Cam Series Cameras","id":"CVE-2025-12463"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat OpenShift Container Platform 4"],"published":"2025-10-31","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-31","vendors":["Red Hat"]},"summary":"A malicious guest user can crash the QEMU host process via a stack buffer overflow in the e1000 network device loopback mode.","url":"https://insights.sbomify.com/CVE-2025-12464/"}
