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-2022-4435 in the wild and no public exploit code.\n\nAffected product: Lenovo ThinkPad X13s. 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-2022-4435/ (Markdown: https://insights.sbomify.com/CVE-2022-4435/index.md)","id":"CVE-2022-4435","markdown":"https://insights.sbomify.com/CVE-2022-4435/index.md","name":"CVE-2022-4435","record":{"aliases":["GHSA-h3fq-3f4x-hmfh"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ThinkPad X13s BIOS","requires_auth":"high_privilege","summary":"A local attacker with elevated privileges can exploit a buffer over-read in the BIOS to disclose sensitive information.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"thinkpad_x13s_firmware","vendor":"lenovo"}],"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-125","name":"Out-of-bounds Read"},{"id":"CWE-126","name":"Buffer Over-read"}],"description":"A buffer over-read vulnerability was reported in the ThinkPadX13s BIOS LenovoRemoteConfigUpdateDxe driver that could allow a local attacker with elevated privileges to cause information disclosure.","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 ThinkPad X13s","id":"CVE-2022-4435","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in Chrome","id":"CVE-2022-4436"},"packages":[],"prev":{"headline":"Information disclosure in ThinkPad X13s","id":"CVE-2022-4434"},"products":["ThinkPad X13s"],"published":"2023-01-05","related":[{"cvss_score":6.7,"headline":"Information disclosure in ThinkPad X13s","id":"CVE-2022-4432","kev_date_added":null,"published":"2023-01-05"},{"cvss_score":6.7,"headline":"Information disclosure in ThinkPad X13s","id":"CVE-2022-4433","kev_date_added":null,"published":"2023-01-05"},{"cvss_score":6.7,"headline":"Information disclosure in ThinkPad X13s","id":"CVE-2022-4434","kev_date_added":null,"published":"2023-01-05"}],"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":"total"},"state":"PUBLISHED","updated":"2025-04-10","vendors":["Lenovo"]},"summary":"A local attacker with elevated privileges can exploit a buffer over-read in the BIOS to disclose sensitive information.","url":"https://insights.sbomify.com/CVE-2022-4435/"}
