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-2025-52536 in the wild and no public exploit code.\n\nAffected product: AMD EPYC™ 7003 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-2025-52536/ (Markdown: https://insights.sbomify.com/CVE-2025-52536/index.md)","id":"CVE-2025-52536","markdown":"https://insights.sbomify.com/CVE-2025-52536/index.md","name":"CVE-2025-52536","record":{"aliases":["DEBIAN-CVE-2025-52536","GHSA-546x-462h-qqw8","UBUNTU-CVE-2025-52536"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD EPYC firmware","requires_auth":"high_privilege","summary":"A privileged attacker can downgrade SEV firmware due to improper lock bit prevention, compromising system integrity on AMD EPYC processors.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1231","name":"Improper Prevention of Lock Bit Modification"}],"description":"Improper Prevention of Lock Bit Modification in SEV firmware could allow a privileged attacker to downgrade firmware potentially resulting in a loss of 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":"Security feature bypass in AMD EPYC™ 7003 Series Processors","id":"CVE-2025-52536","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Integer overflow in Xilinx Run Time (XRT)","id":"CVE-2025-52538"},"packages":[],"prev":{"headline":"Memory corruption in AMD EPYC™ 9005 Series Processors","id":"CVE-2025-52534"},"products":["AMD EPYC™ 7003 Series Processors","AMD EPYC™ 8004 Series Processors","AMD EPYC™ 9004 Series Processors","AMD EPYC™ 9005 Series Processors","AMD EPYC™ Embedded 7003 Series Processors","AMD EPYC™ Embedded 8004 Series Processors","AMD EPYC™ Embedded 9004 Series Processors (formerly codenamed \"Bergamo\")","AMD EPYC™ Embedded 9004 Series Processors (formerly codenamed \"Genoa\")","AMD EPYC™ Embedded 9005 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 privileged attacker can downgrade SEV firmware due to improper lock bit prevention, compromising system integrity on AMD EPYC processors.","url":"https://insights.sbomify.com/CVE-2025-52536/"}
