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-2021-46757 and fix it if it is affected.\n\nWhat it is: CVE-2021-46757 is a high-severity memory corruption vulnerability in AMD Ryzen™ Embedded 5000, published on 13 Feb 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-2021-46757 in the wild and no public exploit code.\n\nAffected product: AMD Ryzen™ Embedded 5000. 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-2021-46757/ (Markdown: https://insights.sbomify.com/CVE-2021-46757/index.md)","id":"CVE-2021-46757","markdown":"https://insights.sbomify.com/CVE-2021-46757/index.md","name":"CVE-2021-46757","record":{"aliases":["GHSA-5fqp-6xx2-943w"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD Secure OS","requires_auth":"low_privilege","summary":"A malicious Trusted Application can exploit insufficient memory checks in AMD Secure OS to read or write kernel memory, leading to privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[{"product":"ryzen_embedded_5600e_firmware","vendor":"amd"},{"product":"ryzen_embedded_5800e_firmware","vendor":"amd"},{"product":"ryzen_embedded_5900e_firmware","vendor":"amd"},{"product":"ryzen_embedded_5950e_firmware","vendor":"amd"},{"product":"ryzen_embedded_r2312_firmware","vendor":"amd"},{"product":"ryzen_embedded_r2314_firmware","vendor":"amd"},{"product":"ryzen_embedded_v2516_firmware","vendor":"amd"},{"product":"ryzen_embedded_v2546_firmware","vendor":"amd"},{"product":"ryzen_embedded_v2718_firmware","vendor":"amd"},{"product":"ryzen_embedded_v2748_firmware","vendor":"amd"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Insufficient checking of memory buffer in ASP\nSecure OS may allow an attacker with a malicious TA to read/write to the ASP\nSecure OS kernel virtual address space potentially leading to privilege\nescalation.","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 Ryzen™ Embedded 5000","id":"CVE-2021-46757","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in AMD Ryzen™ 5000 Series Processors with Radeon™ Graphics “Barcelo”","id":"CVE-2021-46758"},"packages":[],"prev":{"headline":"Denial of service in 1st Gen AMD EPYC™ Processors","id":"CVE-2021-46756"},"products":["AMD Ryzen™ Embedded 5000","AMD Ryzen™ Embedded V2000"],"published":"2024-02-13","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-05-07","vendors":["AMD"]},"summary":"A malicious Trusted Application can exploit insufficient memory checks in AMD Secure OS to read or write kernel memory, leading to privilege escalation.","url":"https://insights.sbomify.com/CVE-2021-46757/"}
