It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-20576 and fix it if it is affected.\n\nWhat it is: CVE-2023-20576 is a high-severity vulnerability in AMD Ryzen™ 3000 Series Desktop Processors, published on 2 Sep 2026. 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-2023-20576 in the wild and no public exploit code.\n\nAffected product: AMD Ryzen™ 3000 Series Desktop 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-2023-20576/ (Markdown: https://insights.sbomify.com/CVE-2023-20576/index.md)","id":"CVE-2023-20576","markdown":"https://insights.sbomify.com/CVE-2023-20576/index.md","name":"CVE-2023-20576","record":{"aliases":["GHSA-r5qj-42x4-3599"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD Ryzen processors","requires_auth":"none","summary":"Insufficient data authenticity verification in AMD AGESA firmware allows attackers to modify SPI ROM, leading to privilege escalation or denial of service.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Insufficient Verification of Data Authenticity in AGESA™ may allow an attacker to update SPI ROM data potentially resulting in denial of service or privilege escalation.","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":"Security feature bypass in AMD Ryzen™ 3000 Series Desktop Processors","id":"CVE-2023-20576","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in 2nd Gen AMD EPYC™ Processors","id":"CVE-2023-20577"},"packages":[],"prev":{"headline":"Information disclosure in 1st Gen AMD EPYC™ Processors","id":"CVE-2023-20575"},"products":["AMD Ryzen™ 3000 Series Desktop Processors","AMD Ryzen™ 4000 Series Desktop Processors with Radeon™ Graphics","AMD Ryzen™ 5000 Series Desktop Processors","AMD Ryzen™ 5000 Series Desktop Processors with Radeon™ Graphics","AMD Ryzen™ 6000 Series Processors with Radeon™ Graphics","AMD Ryzen™ 7000 Series Processors","AMD Ryzen™ 7020 Series Processors with Radeon™ Graphics","AMD Ryzen™ 7035 Series Processors with Radeon™ Graphics","AMD Ryzen™ 7040 Series Processors with Radeon™ Graphics","AMD Ryzen™ 7045 Series Mobile Processors","AMD Ryzen™ Embedded 5000","AMD Ryzen™ Embedded V3000","AMD Ryzen™ Threadripper™ PRO 5000WX Processors"],"published":"2026-09-02","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":"total"},"state":"PUBLISHED","updated":"2026-09-04","vendors":["AMD"]},"summary":"Insufficient data authenticity verification in AMD AGESA firmware allows attackers to modify SPI ROM, leading to privilege escalation or denial of service.","url":"https://insights.sbomify.com/CVE-2023-20576/"}
