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-2026-71337 and fix it if it is affected.\n\nWhat it is: CVE-2026-71337 is a high-severity memory corruption vulnerability in Microsoft Windows 10 21h2, published on 8 Sep 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-2026-71337 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 10 21h2. 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-2026-71337/ (Markdown: https://insights.sbomify.com/CVE-2026-71337/index.md)","id":"CVE-2026-71337","markdown":"https://insights.sbomify.com/CVE-2026-71337/index.md","name":"CVE-2026-71337","record":{"aliases":["GHSA-66pm-v4mm-q3hw"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Storage Provider","requires_auth":"low_privilege","summary":"A stack-based buffer overflow in Windows Storage Management Provider allows local attackers to elevate privileges.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_21h2","vendor":"microsoft"},{"product":"windows_10_22h2","vendor":"microsoft"},{"product":"windows_11_23h2","vendor":"microsoft"},{"product":"windows_11_24h2","vendor":"microsoft"},{"product":"windows_11_25h2","vendor":"microsoft"},{"product":"windows_11_26h1","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-130","name":"Improper Handling of Length Parameter Inconsistency"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Stack-based buffer overflow in Windows Storage Management Provider 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 Storage Management Provider Elevation of Privilege Vulnerability","id":"CVE-2026-71337","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10_21h2","products":["microsoft:windows_10_21h2","microsoft:windows_10_22h2","microsoft:windows_11_23h2","microsoft:windows_11_24h2","microsoft:windows_11_25h2","microsoft:windows_11_26h1","microsoft:windows_server_2022","microsoft:windows_server_2025"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Failover Cluster Elevation of Privilege Vulnerability","id":"CVE-2026-71338"},"packages":[],"prev":{"headline":"Windows Work Folder Service Remote Code Execution Vulnerability","id":"CVE-2026-71336"},"products":["Windows 10 Version 21H2","Windows 10 Version 22H2","Windows 11 Version 23H2","Windows 11 Version 24H2","Windows 11 Version 25H2","Windows 11 version 23H2","Windows 11 version 26H1","Windows Server 2022","Windows Server 2025","Windows Server 2025 (Server Core installation)"],"published":"2026-09-08","related":[{"cvss_score":7.8,"headline":"Microsoft Windows Hyper-V NT Kernel Integration VSP Heap-based Buffer Overflow","id":"CVE-2025-21333","kev_date_added":"2025-01-14","published":"2025-01-14"},{"cvss_score":7.8,"headline":"Microsoft Windows Hyper-V NT Kernel Integration VSP Use-After-Free","id":"CVE-2025-21334","kev_date_added":"2025-01-14","published":"2025-01-14"},{"cvss_score":7.8,"headline":"Microsoft Windows Hyper-V NT Kernel Integration VSP Use-After-Free","id":"CVE-2025-21335","kev_date_added":"2025-01-14","published":"2025-01-14"},{"cvss_score":9.6,"headline":"Windows TCP/IP Elevation of Privilege Vulnerability","id":"CVE-2026-42904","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":8.8,"headline":"Windows Hyper-V Remote Code Execution Vulnerability","id":"CVE-2026-105733","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":"Windows AppX Deployment Extensions Elevation of Privilege Vulnerability","id":"CVE-2026-69945","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":"Windows Graphics Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-88073","kev_date_added":null,"published":"2026-10-13"}],"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":"2026-10-14","vendors":["Microsoft"]},"summary":"A stack-based buffer overflow in Windows Storage Management Provider allows local attackers to elevate privileges.","url":"https://insights.sbomify.com/CVE-2026-71337/"}
