Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-31364 and fix it if it is affected.\n\nWhat it is: CVE-2023-31364 is a high-severity denial of service vulnerability in AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics, published on 26 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-31364 in the wild and no public exploit code.\n\nAffected product: AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics. 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-2023-31364/ (Markdown: https://insights.sbomify.com/CVE-2023-31364/index.md)","id":"CVE-2023-31364","markdown":"https://insights.sbomify.com/CVE-2023-31364/index.md","name":"CVE-2023-31364","record":{"aliases":["GHSA-xxv2-rmf4-wfx2"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"AMD EPYC processors","requires_auth":"low_privilege","summary":"A malicious guest VM can flood the host with memory writes via the IOMMU, causing a fatal machine check error and denial of service on AMD EPYC systems.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Improper handling of direct memory writes in the input-output memory management unit could allow a malicious guest virtual machine (VM) to flood a host with writes, potentially causing a fatal machine check error resulting in 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":null,"headline":"Denial of service in AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics","id":"CVE-2023-31364","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Integer overflow in AMD Radeon™ PRO V710 Graphics Products","id":"CVE-2023-31365"},"packages":[],"prev":{"headline":"Privilege escalation in AIM-T (AMD Integrated Management Technology) software","id":"CVE-2023-31361"},"products":["AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics","AMD EPYC™ 7001 Series Processors","AMD EPYC™ 7002 Series Processors","AMD EPYC™ 7003 Series Processors","AMD EPYC™ 8004 Series Processors","AMD EPYC™ 9004 Series Processors","AMD EPYC™ 9005 Series Processors","AMD EPYC™ Embedded 3000 Series Processors","AMD EPYC™ Embedded 7002 Series Processors","AMD EPYC™ Embedded 7003 Series Processors","AMD EPYC™ Embedded 8004 Series Processors","AMD EPYC™ Embedded 9004 Series Processor","AMD EPYC™ Embedded 9005 Series Processors","AMD Ryzen™ 3000 Series Desktop Processors","AMD Ryzen™ 3000 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ 4000 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ 5000 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ 6000 Series Processors with Radeon™ Graphics","AMD Ryzen™ 7000 Series Desktop Processors","AMD Ryzen™ 7020 Series Processors with Radeon™ Graphics","AMD Ryzen™ 7040 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ 7045 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ 8000 Series Desktop Processors","AMD Ryzen™ Embedded 5000 Series Processors","AMD Ryzen™ Embedded 7000 Series Processors","AMD Ryzen™ Embedded 8000 Series Processors","AMD Ryzen™ Embedded R1000 Series Processors","AMD Ryzen™ Embedded R2000 Series Processors","AMD Ryzen™ Embedded V1000 Series Processors","AMD Ryzen™ Embedded V2000 Series Processors","AMD Ryzen™ Embedded V3000 Series Processors","AMD Ryzen™ Threadripper™ PRO 3000 WX-Series Processors","AMD Ryzen™ Threadripper™ PRO 5000 WX-Series Processors"],"published":"2026-02-26","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":"2026-02-27","vendors":["AMD"]},"summary":"A malicious guest VM can flood the host with memory writes via the IOMMU, causing a fatal machine check error and denial of service on AMD EPYC systems.","url":"https://insights.sbomify.com/CVE-2023-31364/"}
