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-2026-69544 and fix it if it is affected.\n\nWhat it is: CVE-2026-69544 is a high-severity memory corruption vulnerability in Microsoft Windows 11 26h1, 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-2026-69544 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 11 26h1. 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-2026-69544/ (Markdown: https://insights.sbomify.com/CVE-2026-69544/index.md)","id":"CVE-2026-69544","markdown":"https://insights.sbomify.com/CVE-2026-69544/index.md","name":"CVE-2026-69544","record":{"aliases":["GHSA-4qx9-g9wc-38c2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows SMB Client","requires_auth":"low_privilege","summary":"A heap-based buffer overflow in the Windows SMB Client allows an authorized local attacker to elevate privileges.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_11_26h1","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-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based buffer overflow in Windows SMB Client 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 SMB Client Elevation of Privilege Vulnerability","id":"CVE-2026-69544","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_11_26h1","products":["microsoft:windows_11_26h1"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Active Directory Domain Services Remote Code Execution Vulnerability","id":"CVE-2026-69546"},"packages":[],"prev":{"headline":"Azure Virtual Machines Elevation of Privilege Vulnerability","id":"CVE-2026-69543"},"products":["Windows 11 version 26H1"],"published":"2026-09-08","related":[{"cvss_score":8.2,"headline":"Windows Secure Kernel Mode Elevation of Privilege Vulnerability","id":"CVE-2026-85921","kev_date_added":null,"published":"2026-09-14"},{"cvss_score":8.2,"headline":"Windows Secure Kernel Mode Elevation of Privilege Vulnerability","id":"CVE-2026-83939","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":8.1,"headline":"Windows Schannel Remote Code Execution Vulnerability","id":"CVE-2026-105005","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":7.8,"headline":"Windows Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-85850","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":7.8,"headline":"Windows Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-97803","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":7.8,"headline":"Windows Container Isolation FS Filter Driver (unionfs.sys) Elevation of Privilege Vulnerability","id":"CVE-2026-62772","kev_date_added":null,"published":"2026-08-11"}],"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 heap-based buffer overflow in the Windows SMB Client allows an authorized local attacker to elevate privileges.","url":"https://insights.sbomify.com/CVE-2026-69544/"}
