An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-20511 in the wild and no public exploit code.\n\nAffected product: AMD Radeon™ Instinct™ MI25 Graphics Products. 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-2023-20511/ (Markdown: https://insights.sbomify.com/CVE-2023-20511/index.md)","id":"CVE-2023-20511","markdown":"https://insights.sbomify.com/CVE-2023-20511/index.md","name":"CVE-2023-20511","record":{"aliases":["GHSA-98r8-gv3j-w3m9"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"AMD GPU driver","requires_auth":"high_privilege","summary":"A privileged attacker can exploit a double free in the AMD kernel mode driver to achieve arbitrary code execution.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-763","name":"Release of Invalid Pointer or Reference"}],"description":"Release of an invalid pointer in the AMD kernel mode driver (KMD) could allow a privileged attacker to create a double free condition potentially leading to arbitrary code execution.","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":"Use after free in AMD Radeon™ Instinct™ MI25 Graphics Products","id":"CVE-2023-20511","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded credentials in AMD Radeon™ PRO W6000 Series Graphics Cards","id":"CVE-2023-20512"},"packages":[],"prev":{"headline":"Denial of service in AMD Radeon™ PRO W6000 Series Graphics Cards","id":"CVE-2023-20510"},"products":["AMD Radeon™ Instinct™ MI25 Graphics Products","AMD Radeon™ PRO V620 Graphics Products"],"published":"2026-08-31","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":"total"},"state":"PUBLISHED","updated":"2026-09-01","vendors":["AMD"]},"summary":"A privileged attacker can exploit a double free in the AMD kernel mode driver to achieve arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2023-20511/"}
