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-2023-20583 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-2023-20583/ (Markdown: https://insights.sbomify.com/CVE-2023-20583/index.md)","id":"CVE-2023-20583","markdown":"https://insights.sbomify.com/CVE-2023-20583/index.md","name":"CVE-2023-20583","record":{"aliases":["GHSA-52f4-rvv8-64gj"],"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":"low_privilege","summary":"An authenticated attacker can monitor CPU power consumption to leak sensitive information from cache lines on AMD processors.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMD","cpe":[{"product":"*","vendor":"amd"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"A potential power side-channel vulnerability in\nAMD processors may allow an authenticated attacker to monitor the CPU power\nconsumption as the data in a cache line changes over time potentially resulting\nin a leak of sensitive information.","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":"Software based Power Side Channel on AMD CPUs","id":"CVE-2023-20583","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in AMD EPYC™ 7003 Processors","id":"CVE-2023-20584"},"packages":[],"prev":{"headline":"Security feature bypass in AMD EPYC™ 9004 Processors","id":"CVE-2023-20582"},"products":["Processors"],"published":"2023-08-01","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":"2024-10-17","vendors":["AMD"]},"summary":"An authenticated attacker can monitor CPU power consumption to leak sensitive information from cache lines on AMD processors.","url":"https://insights.sbomify.com/CVE-2023-20583/"}
