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-2026-57968 and fix it if it is affected.\n\nWhat it is: CVE-2026-57968 is a high-severity memory corruption vulnerability in Microsoft Windows Subsystem for Linux (WSL2), published on 14 Jul 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-2026-57968 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows Subsystem for Linux (WSL2). 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-2026-57968/ (Markdown: https://insights.sbomify.com/CVE-2026-57968/index.md)","id":"CVE-2026-57968","markdown":"https://insights.sbomify.com/CVE-2026-57968/index.md","name":"CVE-2026-57968","record":{"aliases":["GHSA-ffj6-89cj-pgr8"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Subsystem for Linux","requires_auth":"low_privilege","summary":"An authorized local attacker can exploit a buffer over-read in WSL2 to elevate privileges on the host system.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_subsystem_for_linux","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-126","name":"Buffer Over-read"}],"description":"Buffer over-read in Windows Subsystem for Linux 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":false,"headline":"Windows Subsystem for Linux (WSL2) Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-57968","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Azure CycleCloud Elevation of Privilege Vulnerability","id":"CVE-2026-57969"},"packages":[],"prev":{"headline":"Apache Artemis, Apache ActiveMQ Artemis: Missing authentication on CORE protocol session reattachment","id":"CVE-2026-57967"},"products":["Windows Subsystem for Linux (WSL2)"],"published":"2026-07-14","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":8.8,"headline":"Windows Subsystem for Linux GUI Remote Code Execution Vulnerability","id":"CVE-2025-62220","kev_date_added":null,"published":"2025-11-11"},{"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":"2026-10-28","vendors":["Microsoft"]},"summary":"An authorized local attacker can exploit a buffer over-read in WSL2 to elevate privileges on the host system.","url":"https://insights.sbomify.com/CVE-2026-57968/"}
