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-2021-26387 and fix it if it is affected.\n\nWhat it is: CVE-2021-26387 is a low-severity missing authorization vulnerability in AMD Athlon™ 3000 Series Desktop Processors with Radeon™ Graphics, published on 13 Aug 2024. 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-2021-26387 in the wild and no public exploit code.\n\nAffected product: AMD Athlon™ 3000 Series Desktop 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-2021-26387/ (Markdown: https://insights.sbomify.com/CVE-2021-26387/index.md)","id":"CVE-2021-26387","markdown":"https://insights.sbomify.com/CVE-2021-26387/index.md","name":"CVE-2021-26387","record":{"aliases":["GHSA-mcm9-3rfg-2mqm"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD processor firmware","requires_auth":"high_privilege","summary":"Privileged attackers with signing keys or UEFI access can bypass memory protections to compromise platform integrity on AMD processors.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[],"cvss":{"score":3.9,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Insufficient access controls in ASP kernel may allow a\nprivileged attacker with access to AMD signing keys and the BIOS menu or UEFI\nshell to map DRAM regions in protected areas, potentially leading to a loss of platform 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":null,"headline":"Missing authorization in AMD Athlon™ 3000 Series Desktop Processors with Radeon™ Graphics","id":"CVE-2021-26387","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in Athlon™ Series","id":"CVE-2021-26388"},"packages":[],"prev":{"headline":"Memory corruption in Athlon™ Series","id":"CVE-2021-26386"},"products":["AMD Athlon™ 3000 Series Desktop Processors with Radeon™ Graphics","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™ 9004 Series Processors","AMD EPYC™ Embedded 3000 Series Processors","AMD EPYC™ Embedded 7002 Series Processors","AMD EPYC™ Embedded 7003 Series Processors","AMD EPYC™ Embedded 9003 Series Processors","AMD Ryzen™ 3000 Series Desktop Processors","AMD Ryzen™ 3000 Series Mobile Processor with Radeon™ Graphics","AMD Ryzen™ 3000 Series Processors with Radeon™ Graphics","AMD Ryzen™ 4000 Series Desktop Processors with Radeon™ Graphics","AMD Ryzen™ 4000 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ 5000 Series Desktop Processor with Radeon™ Graphics","AMD Ryzen™ 5000 Series Desktop Processors","AMD Ryzen™ 5000 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ 5000 Series Processors with Radeon™ Graphics","AMD Ryzen™ 6000 Series Processors with Radeon™ Graphics","AMD Ryzen™ 7000 Series Desktop Processors","AMD Ryzen™ 7035 Series Processors with Radeon™ Graphics","AMD Ryzen™ Embedded 5000 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™ 3000 Series Processors","AMD Ryzen™ Threadripper™ PRO 3000WX Series Processors","AMD Ryzen™ Threadripper™ PRO 5000WX Processors"],"published":"2024-08-13","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":"2024-10-30","vendors":["AMD"]},"summary":"Privileged attackers with signing keys or UEFI access can bypass memory protections to compromise platform integrity on AMD processors.","url":"https://insights.sbomify.com/CVE-2021-26387/"}
