An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-41096 and fix it if it is affected.\n\nWhat it is: CVE-2026-41096 is a critical memory corruption vulnerability in Microsoft Windows 11 23h2, published on 12 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-41096 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 11 23h2. 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-2026-41096/ (Markdown: https://insights.sbomify.com/CVE-2026-41096/index.md)","id":"CVE-2026-41096","markdown":"https://insights.sbomify.com/CVE-2026-41096/index.md","name":"CVE-2026-41096","record":{"aliases":["GHSA-9pgv-xqpg-75rv"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows DNS Client","requires_auth":"none","summary":"An unauthorized attacker can execute arbitrary code remotely via a heap-based buffer overflow in the Windows DNS Client.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"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_23h2","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based buffer overflow in Microsoft Windows DNS allows an unauthorized attacker to execute code over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-02-05","github_poc":7,"max_poc_stars":96,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-02-05T10:21:22Z","kind":"github_poc","ref":"https://github.com/ZeroDayEvil/CVE-2026-41096-PoC","stars":96,"title":"🛡️ Official AI Security Tool module for CVE-2026-41096 (Windows DNSAPI.dll Heap Overflow / DNS-Mayhem Deep Dive Analysis \u0026 Audit Module)."},{"date":"2026-05-24T00:46:09Z","kind":"github_poc","ref":"https://github.com/satchfunky/CVE-2026-41096-POC","stars":39,"title":"windows api bug"},{"date":"2026-06-04T14:11:54Z","kind":"github_poc","ref":"https://github.com/TwoSevenOneT/CVE-2026-41096-Attack-Surface","stars":15,"title":"Attack surface in the real-world environment of CVE-2026-41096"},{"date":"2026-05-15T07:30:24Z","kind":"github_poc","ref":"https://github.com/mrk336/DNS-Mayhem-CVE-2026-41096-Deep-Dive","stars":4,"title":"In‑depth technical analysis of CVE‑2026‑41096, a critical heap overflow in Windows DNSAPI.dll enabling remote code execution via crafted DNS responses.
