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-2021-46766 in the wild and no public exploit code.\n\nAffected product: 4th Gen AMD EPYC™ 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-2021-46766/ (Markdown: https://insights.sbomify.com/CVE-2021-46766/index.md)","id":"CVE-2021-46766","markdown":"https://insights.sbomify.com/CVE-2021-46766/index.md","name":"CVE-2021-46766","record":{"aliases":["GHSA-34xr-h92c-2m86"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD EPYC firmware","requires_auth":"high_privilege","summary":"A privileged attacker can access secret keys from ASP SRAM due to improper data clearing in AMD EPYC bootloader firmware.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[{"product":"epyc_9124_firmware","vendor":"amd"},{"product":"epyc_9174f_firmware","vendor":"amd"},{"product":"epyc_9184x_firmware","vendor":"amd"},{"product":"epyc_9224_firmware","vendor":"amd"},{"product":"epyc_9254_firmware","vendor":"amd"},{"product":"epyc_9274f_firmware","vendor":"amd"},{"product":"epyc_9334_firmware","vendor":"amd"},{"product":"epyc_9354_firmware","vendor":"amd"},{"product":"epyc_9354p_firmware","vendor":"amd"},{"product":"epyc_9374f_firmware","vendor":"amd"},{"product":"epyc_9384x_firmware","vendor":"amd"},{"product":"epyc_9454_firmware","vendor":"amd"},{"product":"epyc_9454p_firmware","vendor":"amd"},{"product":"epyc_9474f_firmware","vendor":"amd"},{"product":"epyc_9534_firmware","vendor":"amd"},{"product":"epyc_9554_firmware","vendor":"amd"},{"product":"epyc_9554p_firmware","vendor":"amd"},{"product":"epyc_9634_firmware","vendor":"amd"},{"product":"epyc_9654_firmware","vendor":"amd"},{"product":"epyc_9654p_firmware","vendor":"amd"},{"product":"epyc_9684x_firmware","vendor":"amd"},{"product":"epyc_9734_firmware","vendor":"amd"},{"product":"epyc_9754_firmware","vendor":"amd"},{"product":"epyc_9754s_firmware","vendor":"amd"},{"product":"ryzen_threadripper_pro_3945wx_firmware","vendor":"amd"},{"product":"ryzen_threadripper_pro_3955wx_firmware","vendor":"amd"},{"product":"ryzen_threadripper_pro_3975wx_firmware","vendor":"amd"},{"product":"ryzen_threadripper_pro_3995wx_firmware","vendor":"amd"}],"cvss":{"score":2.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-459","name":"Incomplete Cleanup"}],"description":"Improper clearing of sensitive data in the ASP Bootloader may expose secret keys to a privileged attacker accessing ASP SRAM, potentially leading to a loss of confidentiality.","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":"Information disclosure in 4th Gen AMD EPYC™ Processors","id":"CVE-2021-46766","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Other in 2nd Gen EPYC","id":"CVE-2021-46767"},"packages":[],"prev":{"headline":"Denial of service in Ryzen™ 3000 Series Mobile Processors with Radeon™ Graphics “Renoir”","id":"CVE-2021-46765"},"products":["4th Gen AMD EPYC™ Processors","AMD EPYC™ Embedded 9003","Ryzen™ Threadripper™ PRO 3000WX Series Processors  “Chagall” WS"],"published":"2023-11-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["AMD"]},"summary":"A privileged attacker can access secret keys from ASP SRAM due to improper data clearing in AMD EPYC bootloader firmware.","url":"https://insights.sbomify.com/CVE-2021-46766/"}
