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-2023-20519 in the wild and no public exploit code.\n\nAffected product: 3rd Gen AMD EPYC™ Processors. 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-2023-20519/ (Markdown: https://insights.sbomify.com/CVE-2023-20519/index.md)","id":"CVE-2023-20519","markdown":"https://insights.sbomify.com/CVE-2023-20519/index.md","name":"CVE-2023-20519","record":{"aliases":["GHSA-3pww-pqg2-m2hm"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD EPYC Processors","requires_auth":"low_privilege","summary":"A malicious hypervisor can exploit a use-after-free flaw in AMD EPYC processors to masquerade as a migration agent, compromising guest integrity.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[{"product":"genoapi_firmware","vendor":"amd"},{"product":"milanpi_firmware","vendor":"amd"}],"cvss":{"score":3.3,"severity":"low","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A Use-After-Free vulnerability in the management of an SNP guest context page may allow a malicious hypervisor to masquerade as the guest's migration agent resulting in a potential loss of guest integrity.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Use after free in 3rd Gen AMD EPYC™ Processors","id":"CVE-2023-20519","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":"Memory corruption in 1st Gen AMD EPYC™","id":"CVE-2023-20520"},"packages":[],"prev":{"headline":"Information disclosure in AMD Athlon™ 3000 Series Desktop Processors with Radeon™ Graphics","id":"CVE-2023-20518"},"products":["3rd Gen AMD EPYC™ Processors","4th Gen AMD EPYC™ Processors "],"published":"2023-11-14","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":"partial"},"state":"PUBLISHED","updated":"2024-08-30","vendors":[" AMD","AMD"]},"summary":"A malicious hypervisor can exploit a use-after-free flaw in AMD EPYC processors to masquerade as a migration agent, compromising guest integrity.","url":"https://insights.sbomify.com/CVE-2023-20519/"}
