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-2021-0147 in the wild and no public exploit code.\n\nAffected product: Intel Chipset 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-2021-0147/ (Markdown: https://insights.sbomify.com/CVE-2021-0147/index.md)","id":"CVE-2021-0147","markdown":"https://insights.sbomify.com/CVE-2021-0147/index.md","name":"CVE-2021-0147","record":{"aliases":["GHSA-hfj6-rq3w-f48r"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel Chipset firmware","requires_auth":"high_privilege","summary":"A privileged local attacker can cause a denial of service in Intel Chipset firmware due to improper locking in the Power Management Controller.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[{"product":"power_management_controller","vendor":"intel"}],"cvss":{"score":4.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"}],"description":"Improper locking in the Power Management Controller (PMC) for some Intel Chipset firmware before versions pmc_fw_lbg_c1-21ww02a and pmc_fw_lbg_b0-21ww02a may allow a privileged user to potentially enable denial of service via local access.","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":"Race condition in Intel Chipset firmware","id":"CVE-2021-0147","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Intel(R) SSD DC","id":"CVE-2021-0148"},"packages":[],"prev":{"headline":"Privilege escalation in Intel(R) processors which","id":"CVE-2021-0146"},"products":["Intel Chipset firmware"],"published":"2022-02-09","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":"2025-05-05","vendors":["n/a"]},"summary":"A privileged local attacker can cause a denial of service in Intel Chipset firmware due to improper locking in the Power Management Controller.","url":"https://insights.sbomify.com/CVE-2021-0147/"}
