An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-54990 and fix it if it is affected.\n\nWhat it is: CVE-2026-54990 is a critical memory corruption vulnerability in Microsoft Windows 11 24h2, published on 14 Jul 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-2026-54990 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-2026-54990/ (Markdown: https://insights.sbomify.com/CVE-2026-54990/index.md)","id":"CVE-2026-54990","markdown":"https://insights.sbomify.com/CVE-2026-54990/index.md","name":"CVE-2026-54990","record":{"aliases":["GHSA-q6cx-465r-334m"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Remote Desktop Client","requires_auth":"none","summary":"Heap-based buffer overflow in the Remote Desktop Client allows unauthorized attackers to execute code over a network.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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_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 Remote Desktop Client allows an unauthorized attacker to execute code over a network.","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":"Remote Desktop Client Remote Code Execution Vulnerability","id":"CVE-2026-54990","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_server_2025"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows USB Print Driver Elevation of Privilege Vulnerability","id":"CVE-2026-54991"},"packages":[],"prev":{"headline":"Quality Windows Audio/Video Experience (QWAVE) Elevation of Privilege Vulnerability","id":"CVE-2026-54989"},"products":["Windows 11 Version 24H2","Windows 11 Version 25H2","Windows 11 version 26H1","Windows Server 2025","Windows Server 2025 (Server Core installation)"],"published":"2026-07-14","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":"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-28","vendors":["Microsoft"]},"summary":"Heap-based buffer overflow in the Remote Desktop Client allows unauthorized attackers to execute code over a network.","url":"https://insights.sbomify.com/CVE-2026-54990/"}
