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-2021-26327 and fix it if it is affected.\n\nWhat it is: CVE-2021-26327 is a medium-severity vulnerability in Amd Epyc 72f3 Firmware, published on 16 Nov 2021. 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-2021-26327 in the wild and no public exploit code.\n\nAffected product: Amd Epyc 72f3 Firmware. 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-2021-26327/ (Markdown: https://insights.sbomify.com/CVE-2021-26327/index.md)","id":"CVE-2021-26327","markdown":"https://insights.sbomify.com/CVE-2021-26327/index.md","name":"CVE-2021-26327","record":{"aliases":["GHSA-qg7x-g66q-6pmh"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD EPYC firmware","requires_auth":"low_privilege","summary":"Insufficient validation in AMD EPYC SNP firmware allows attackers to potentially compromise guest confidentiality.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[{"product":"epyc_7003_firmware","vendor":"amd"},{"product":"epyc_72f3_firmware","vendor":"amd"},{"product":"epyc_7313_firmware","vendor":"amd"},{"product":"epyc_7313p_firmware","vendor":"amd"},{"product":"epyc_7343_firmware","vendor":"amd"},{"product":"epyc_73f3_firmware","vendor":"amd"},{"product":"epyc_7413_firmware","vendor":"amd"},{"product":"epyc_7443_firmware","vendor":"amd"},{"product":"epyc_7443p_firmware","vendor":"amd"},{"product":"epyc_7453_firmware","vendor":"amd"},{"product":"epyc_74f3_firmware","vendor":"amd"},{"product":"epyc_7513_firmware","vendor":"amd"},{"product":"epyc_7543_firmware","vendor":"amd"},{"product":"epyc_7543p_firmware","vendor":"amd"},{"product":"epyc_75f3_firmware","vendor":"amd"},{"product":"epyc_7643_firmware","vendor":"amd"},{"product":"epyc_7663_firmware","vendor":"amd"},{"product":"epyc_7713_firmware","vendor":"amd"},{"product":"epyc_7713p_firmware","vendor":"amd"},{"product":"epyc_7763_firmware","vendor":"amd"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Insufficient validation of guest context in the SNP Firmware could lead to a potential loss of guest confidentiality.","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":"Information disclosure in 3rd Gen AMD EPYC™","id":"CVE-2021-26327","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"amd:epyc_72f3_firmware","products":["amd:epyc_72f3_firmware","amd:epyc_7313_firmware","amd:epyc_7313p_firmware","amd:epyc_7343_firmware","amd:epyc_73f3_firmware","amd:epyc_7413_firmware","amd:epyc_7443_firmware","amd:epyc_7443p_firmware","amd:epyc_7453_firmware","amd:epyc_74f3_firmware","amd:epyc_7513_firmware","amd:epyc_7543_firmware","amd:epyc_7543p_firmware","amd:epyc_75f3_firmware","amd:epyc_7643_firmware","amd:epyc_7663_firmware","amd:epyc_7713_firmware","amd:epyc_7713p_firmware","amd:epyc_7763_firmware"],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in 3rd Gen EPYC","id":"CVE-2021-26328"},"packages":[],"prev":{"headline":"Memory corruption in 3rd Gen AMD EPYC™","id":"CVE-2021-26326"},"products":["3rd Gen AMD EPYC™"],"published":"2021-11-16","related":[{"cvss_score":7.8,"headline":"Code injection in 3rd Gen AMD EPYC™","id":"CVE-2021-26315","kev_date_added":null,"published":"2021-11-16"},{"cvss_score":7.5,"headline":"Denial of service in 3rd Gen EPYC","id":"CVE-2023-20530","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":5.5,"headline":"Information disclosure in 3rd Gen EPYC","id":"CVE-2021-26343","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":5.5,"headline":"Denial of service in 3rd Gen EPYC","id":"CVE-2021-26355","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":5.5,"headline":"Information disclosure in 3rd Gen EPYC","id":"CVE-2021-26404","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":4.4,"headline":"Information disclosure in 3rd Gen AMD EPYC™ Processors","id":"CVE-2023-20594","kev_date_added":null,"published":"2023-09-20"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["AMD"]},"summary":"Insufficient validation in AMD EPYC SNP firmware allows attackers to potentially compromise guest confidentiality.","url":"https://insights.sbomify.com/CVE-2021-26327/"}
