It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-83751 and fix it if it is affected.\n\nWhat it is: CVE-2026-83751 is a high-severity use after free vulnerability in Microsoft Windows 11 24h2, published on 13 Oct 2026. 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-2026-83751 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 11 24h2. 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-2026-83751/ (Markdown: https://insights.sbomify.com/CVE-2026-83751/index.md)","id":"CVE-2026-83751","markdown":"https://insights.sbomify.com/CVE-2026-83751/index.md","name":"CVE-2026-83751","record":{"aliases":["GHSA-3jhj-r7m8-q8vp"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows MIDI Service","requires_auth":"low_privilege","summary":"An authorized local attacker can exploit a use-after-free flaw in the Windows MIDI Service to elevate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_11_24h2","vendor":"microsoft"},{"product":"windows_11_25h2","vendor":"microsoft"},{"product":"windows_11_26h1","vendor":"microsoft"},{"product":"windows_11_26h2","vendor":"microsoft"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use after free in Windows MIDI Service Module allows an authorized attacker to elevate privileges locally.","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":"Windows MIDI Service Module Elevation of Privileges Vulnerability","id":"CVE-2026-83751","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_11_24h2","products":["microsoft:windows_11_24h2","microsoft:windows_11_25h2","microsoft:windows_11_26h1","microsoft:windows_11_26h2"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Installer Elevation of Privilege Vulnerability","id":"CVE-2026-83752"},"packages":[],"prev":{"headline":"Windows Error Reporting Elevation of Privilege Vulnerability","id":"CVE-2026-83750"},"products":["Windows 11 Version 24H2","Windows 11 Version 25H2","Windows 11 Version 26H2","Windows 11 version 26H1"],"published":"2026-10-13","related":[{"cvss_score":7.8,"headline":"Microsoft Windows Link Following","id":"CVE-2025-60710","kev_date_added":"2026-04-13","published":"2025-11-11"},{"cvss_score":9.8,"headline":"Remote Desktop Client Remote Code Execution Vulnerability","id":"CVE-2026-54990","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":9.8,"headline":"Windows Graphics Component Remote Code Execution Vulnerability","id":"CVE-2025-50165","kev_date_added":null,"published":"2025-08-12"},{"cvss_score":9.8,"headline":"Windows NTLM V1 Elevation of Privilege Vulnerability","id":"CVE-2025-21311","kev_date_added":null,"published":"2025-01-14"},{"cvss_score":8.8,"headline":"Windows SmartScreen Security Feature Bypass Vulnerability","id":"CVE-2026-108463","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":"Windows Image Acquisition Remote Code Execution Vulnerability","id":"CVE-2026-83523","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":"Microsoft Windows Media Foundation Remote Code Execution Vulnerability","id":"CVE-2026-62744","kev_date_added":null,"published":"2026-09-08"}],"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":"2026-10-29","vendors":["Microsoft"]},"summary":"An authorized local attacker can exploit a use-after-free flaw in the Windows MIDI Service to elevate privileges.","url":"https://insights.sbomify.com/CVE-2026-83751/"}
