It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-9805 and fix it if it is affected.\n\nWhat it is: CVE-2026-9805 is a low-severity memory corruption vulnerability in InsydeH2O, published on 26 Aug 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-9805 in the wild and no public exploit code.\n\nAffected product: InsydeH2O. 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-2026-9805/ (Markdown: https://insights.sbomify.com/CVE-2026-9805/index.md)","id":"CVE-2026-9805","markdown":"https://insights.sbomify.com/CVE-2026-9805/index.md","name":"CVE-2026-9805","record":{"aliases":["GHSA-q9cj-25hp-849c"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"InsydeH2O BIOS","requires_auth":"high_privilege","summary":"A buffer overflow in the InsydeH2O BIOS SMM handler allows attackers to execute arbitrary code with high privileges.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Insyde","cpe":[],"cvss":{"score":2.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:P/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"SMM IHISI command handler, FMTSWriteUseIntelLib, for FMTS command 0x32, read and write data without checking buffer size and could cause buffer overflow.","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":"FMTSWriteUseIntelLib: FMTS SMM IHISI Buffer Overflow","id":"CVE-2026-9805","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":"Stored Cross-Site Scripting (XSS) in CTI Transmute Notification Panel via Malicious Convert Names","id":"CVE-2026-9806"},"packages":[],"prev":{"headline":"Kubevirt: kubevirt: vmexport directory symlink escape enables exporter pod file read","id":"CVE-2026-9804"},"products":["InsydeH2O"],"published":"2026-08-26","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":"2026-08-26","vendors":["Insyde Software"]},"summary":"A buffer overflow in the InsydeH2O BIOS SMM handler allows attackers to execute arbitrary code with high privileges.","url":"https://insights.sbomify.com/CVE-2026-9805/"}
