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-2021-46772 and fix it if it is affected.\n\nWhat it is: CVE-2021-46772 is a low-severity memory corruption 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-2021-46772 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-2021-46772/ (Markdown: https://insights.sbomify.com/CVE-2021-46772/index.md)","id":"CVE-2021-46772","markdown":"https://insights.sbomify.com/CVE-2021-46772/index.md","name":"CVE-2021-46772","record":{"aliases":["GHSA-mgjx-cq94-rwcv"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD CPU firmware","requires_auth":"high_privilege","summary":"Privileged attackers with BIOS or UEFI shell access can corrupt memory via SPI ROM tampering, potentially causing code execution or denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-787","name":"Out-of-bounds Write"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Insufficient input validation in the ABL may allow a privileged\nattacker with access to the BIOS menu or UEFI shell to tamper with the\nstructure headers in SPI ROM causing an out of bounds memory read and write,\npotentially resulting in memory corruption or denial of service.","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":"Memory corruption in AMD Athlon™ 3000 Series Desktop Processors with Radeon™ Graphics","id":"CVE-2021-46772","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in 3rd Gen AMD Ryzen™ Threadripper™ Processors “Castle Peak” HEDT","id":"CVE-2021-46773"},"packages":[],"prev":{"headline":"Other in 3rd Gen AMD EPYC™","id":"CVE-2021-46771"},"products":["AMD Athlon™ 3000 Series Desktop Processors with Radeon™ Graphics","AMD Athlon™ 3000 Series Mobile  Processors with Radeon™ Graphics","AMD EPYC™ 7002 Series Processors","AMD EPYC™ 7003 Series Processors","AMD EPYC™ Embedded 7002 Series Processors","AMD EPYC™ Embedded 7003 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™ 7020 Series Processors with Radeon™ Graphics","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":"2024-11-05","vendors":["AMD"]},"summary":"Privileged attackers with BIOS or UEFI shell access can corrupt memory via SPI ROM tampering, potentially causing code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2021-46772/"}
