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-2026-19398 in the wild and no public exploit code.\n\nAffected product: ASUS FA507NU. 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-2026-19398/ (Markdown: https://insights.sbomify.com/CVE-2026-19398/index.md)","id":"CVE-2026-19398","markdown":"https://insights.sbomify.com/CVE-2026-19398/index.md","name":"CVE-2026-19398","record":{"aliases":["GHSA-mqcp-4543-826g"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ASUS BIOS","requires_auth":"high_privilege","summary":"A local administrator can trigger a system crash or BIOS corruption via an out-of-bounds write in the ASUS BIOS SMM module.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ASUS","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An out-of-bounds write in the SmiFlash SMM module of ASUS FA507NU and FA507NV BIOS allows a local  administrator to cause a system crash (BSOD) or BIOS corruption via a crafted software SMI (SW SMI) request with an oversized length value.Refer to the ' \nSecurity Update for ASUS FA507NV / FA507NU BIOS   ' section on the ASUS Security Advisory for more 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":"Memory corruption in FA507NU","id":"CVE-2026-19398","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Remote UDP DoS by sending multiple DNS Cookie options","id":"CVE-2026-19401"},"packages":[],"prev":{"headline":"Missing authorization in Control Center Express Agent","id":"CVE-2026-19397"},"products":["FA507NU","FA507NV"],"published":"2026-08-27","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":"partial"},"state":"PUBLISHED","updated":"2026-09-09","vendors":["ASUS"]},"summary":"A local administrator can trigger a system crash or BIOS corruption via an out-of-bounds write in the ASUS BIOS SMM module.","url":"https://insights.sbomify.com/CVE-2026-19398/"}
