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-2021-26400 in the wild and no public exploit code.\n\nAffected product: AMD 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-2021-26400/ (Markdown: https://insights.sbomify.com/CVE-2021-26400/index.md)","id":"CVE-2021-26400","markdown":"https://insights.sbomify.com/CVE-2021-26400/index.md","name":"CVE-2021-26400","record":{"aliases":["GHSA-p6cf-jjrc-ff28"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"AMD Processors","requires_auth":"none","summary":"AMD processors may leak stale data from shared memory due to speculative re-ordering, allowing attackers to read sensitive information.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[{"product":"cpu","vendor":"amd"}],"cvss":{"score":4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[],"description":"AMD processors may speculatively re-order load instructions which can result in stale data being observed when multiple processors are operating on shared memory, resulting in potential data leakage.","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 AMD Processors","id":"CVE-2021-26400","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in AMD Processors","id":"CVE-2021-26401"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2021-26399"},"products":["AMD Processors"],"published":"2022-05-11","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["AMD"]},"summary":"AMD processors may leak stale data from shared memory due to speculative re-ordering, allowing attackers to read sensitive information.","url":"https://insights.sbomify.com/CVE-2021-26400/"}
