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-2024-21953 in the wild and no public exploit code.\n\nAffected product: AMD EPYC™ 8004 Series Processors. 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-2024-21953/ (Markdown: https://insights.sbomify.com/CVE-2024-21953/index.md)","id":"CVE-2024-21953","markdown":"https://insights.sbomify.com/CVE-2024-21953/index.md","name":"CVE-2024-21953","record":{"aliases":["GHSA-846p-qcjx-5365","UBUNTU-CVE-2024-21953"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD EPYC processors","requires_auth":"high_privilege","summary":"A malicious hypervisor can reconfigure IOMMU registers to compromise guest data integrity on AMD EPYC processors.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:N/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1284","name":"Improper Validation of Specified Quantity in Input"}],"description":"Improper input validation in IOMMU could allow a malicious hypervisor to reconfigure IOMMU registers resulting in loss of guest data integrity.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Other in AMD EPYC™ 8004 Series Processors","id":"CVE-2024-21953","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in AMD Management Console","id":"CVE-2024-21957"},"packages":[],"prev":{"headline":"Information disclosure in AMD Instinct™ MI300A","id":"CVE-2024-21950"},"products":["AMD EPYC™ 8004 Series Processors","AMD EPYC™ 9004 Series Processors","AMD EPYC™ Embedded 9004 Series Processors"],"published":"2026-02-10","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":"2026-02-10","vendors":["AMD"]},"summary":"A malicious hypervisor can reconfigure IOMMU registers to compromise guest data integrity on AMD EPYC processors.","url":"https://insights.sbomify.com/CVE-2024-21953/"}
