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-2021-26383 in the wild and no public exploit code.\n\nAffected product: AMD Instinct™ MI210. 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-2021-26383/ (Markdown: https://insights.sbomify.com/CVE-2021-26383/index.md)","id":"CVE-2021-26383","markdown":"https://insights.sbomify.com/CVE-2021-26383/index.md","name":"CVE-2021-26383","record":{"aliases":["GHSA-89mm-wx6j-wpmg"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD TEE firmware","requires_auth":"high_privilege","summary":"An attacker with compromised userspace can trigger out-of-bounds memory access in AMD TEE, causing integrity or availability loss.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[],"cvss":{"score":7.9,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Insufficient bounds checking in AMD TEE (Trusted Execution Environment) could allow an attacker with a compromised userspace to invoke a command with malformed arguments leading to out of bounds memory access, potentially resulting in loss of integrity or availability.","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 Instinct™ MI210","id":"CVE-2021-26383","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 Athlon™ Series","id":"CVE-2021-26384"},"packages":[],"prev":{"headline":"Security feature bypass in Athlon™ Series","id":"CVE-2021-26382"},"products":["AMD Instinct™ MI210","AMD Instinct™ MI250","AMD Radeon™ PRO V520 Graphics Products","AMD Radeon™ PRO V620 Graphics Products","AMD Radeon™ PRO W5000 Series Graphics Products","AMD Radeon™ PRO W6000 Series Graphics Products","AMD Radeon™ RX 5000 Series Graphics Products","AMD Radeon™ RX 6000 Series Graphics Products","AMD Ryzen™ 4000 Series Desktop Processors","AMD Ryzen™ 4000 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ 5000 Series Desktop Processors with Radeon™ Graphics","AMD Ryzen™ 5000 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ 7030 Series Mobile Processors with Radeon™ Graphics","AMD Ryzen™ Embedded V2000 Series Processors"],"published":"2025-09-05","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":"2025-09-08","vendors":["AMD"]},"summary":"An attacker with compromised userspace can trigger out-of-bounds memory access in AMD TEE, causing integrity or availability loss.","url":"https://insights.sbomify.com/CVE-2021-26383/"}
