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-2023-5912 in the wild and no public exploit code.\n\nAffected product: Lenovo Notebook BIOS. 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-2023-5912/ (Markdown: https://insights.sbomify.com/CVE-2023-5912/index.md)","id":"CVE-2023-5912","markdown":"https://insights.sbomify.com/CVE-2023-5912/index.md","name":"CVE-2023-5912","record":{"aliases":["GHSA-3w26-vfvh-2v33"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lenovo Notebook BIOS","requires_auth":"high_privilege","summary":"A local attacker with elevated privileges can exploit a memory leakage vulnerability in Lenovo Notebook BIOS to write to NVRAM variables.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A potential memory leakage vulnerability was reported in some Lenovo Notebook products that may allow a local attacker with elevated privileges to write to NVRAM variables.","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":"Memory corruption in Notebook BIOS","id":"CVE-2023-5912","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"A potential Privilege Escalation vulnerability in opentext Fortify ScanCentral DAST API.","id":"CVE-2023-5913"},"packages":[],"prev":{"headline":"WP Custom Cursors \u003c= 3.2 - Admin+ Stored XSS","id":"CVE-2023-5911"},"products":["Notebook BIOS"],"published":"2024-04-05","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"total"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["Lenovo"]},"summary":"A local attacker with elevated privileges can exploit a memory leakage vulnerability in Lenovo Notebook BIOS to write to NVRAM variables.","url":"https://insights.sbomify.com/CVE-2023-5912/"}
