An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2025-62220 and fix it if it is affected.\n\nWhat it is: CVE-2025-62220 is a high-severity memory corruption vulnerability in Microsoft Windows Subsystem for Linux GUI, published on 11 Nov 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-62220 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows Subsystem for Linux GUI. 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-2025-62220/ (Markdown: https://insights.sbomify.com/CVE-2025-62220/index.md)","id":"CVE-2025-62220","markdown":"https://insights.sbomify.com/CVE-2025-62220/index.md","name":"CVE-2025-62220","record":{"aliases":["GHSA-q774-gvh6-h2cc"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Subsystem for Linux","requires_auth":"none","summary":"Heap-based buffer overflow in WSL GUI allows remote attackers to execute arbitrary code over the network.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_subsystem_for_linux","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/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 Subsystem for Linux GUI 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":false,"headline":"Windows Subsystem for Linux GUI Remote Code Execution Vulnerability","id":"CVE-2025-62220","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Windows Use After Free","id":"CVE-2025-62221"},"packages":[],"prev":{"headline":"Microsoft Wireless Provisioning System Elevation of Privilege Vulnerability","id":"CVE-2025-62219"},"products":["Windows Subsystem for Linux GUI"],"published":"2025-11-11","related":[{"cvss_score":9.8,"headline":"Visual Studio Code WSL Extension Remote Code Execution Vulnerability","id":"CVE-2021-43907","kev_date_added":null,"published":"2021-12-15"},{"cvss_score":7.8,"headline":"Windows Subsystem for Linux (WSL2) Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-57968","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":7,"headline":"Windows Subsystem for Linux Elevation of Privilege Vulnerability","id":"CVE-2026-85879","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":7,"headline":"Windows Subsystem for Linux (WSL2) Kernel Elevation of Privilege Vulnerability","id":"CVE-2025-53788","kev_date_added":null,"published":"2025-08-12"},{"cvss_score":6.5,"headline":"Windows Subsystem for Linux Information Disclosure Vulnerability","id":"CVE-2026-96206","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":6.3,"headline":"Windows Subsystem for Linux (WSL2) Kernel Tampering Vulnerability","id":"CVE-2026-57973","kev_date_added":null,"published":"2026-07-14"}],"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":"2026-02-26","vendors":["Microsoft"]},"summary":"Heap-based buffer overflow in WSL GUI allows remote attackers to execute arbitrary code over the network.","url":"https://insights.sbomify.com/CVE-2025-62220/"}
