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-2023-20564 in the wild and no public exploit code.\n\nAffected product: AMD Ryzen™ Master. 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-2023-20564/ (Markdown: https://insights.sbomify.com/CVE-2023-20564/index.md)","id":"CVE-2023-20564","markdown":"https://insights.sbomify.com/CVE-2023-20564/index.md","name":"CVE-2023-20564","record":{"aliases":["GHSA-vxhh-8p3q-886v"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD Ryzen Master","requires_auth":"high_privilege","summary":"A privileged attacker can exploit insufficient IOCTL validation in AMD Ryzen Master to perform memory reads/writes, potentially leading to arbitrary kernel execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[{"product":"ryzen_master","vendor":"amd"},{"product":"ryzen_master_monitoring_sdk","vendor":"amd"}],"cvss":{"score":6.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Insufficient validation in the IOCTL (Input Output Control) input buffer in AMD Ryzen™ Master may permit a privileged attacker to perform memory reads/writes potentially leading to a loss of confidentiality or arbitrary kernel execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-11-18","github_poc":1,"max_poc_stars":20,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-11-18T12:59:55Z","kind":"github_poc","ref":"https://github.com/NtGabrielGomes/CVE-2023-20564","stars":20,"title":"PoC for AMD Ryzen driver.
