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-2026-62840 and fix it if it is affected.\n\nWhat it is: CVE-2026-62840 is a high-severity vulnerability in Microsoft Linux 3P (Third Party) Distros, published on 13 Oct 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-2026-62840 in the wild and no public exploit code.\n\nAffected product: Microsoft Linux 3P (Third Party) Distros. 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-2026-62840/ (Markdown: https://insights.sbomify.com/CVE-2026-62840/index.md)","id":"CVE-2026-62840","markdown":"https://insights.sbomify.com/CVE-2026-62840/index.md","name":"CVE-2026-62840","record":{"aliases":["GHSA-2w6f-cwvw-5j95"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux Kernel","requires_auth":"low_privilege","summary":"A time-of-check time-of-use race condition in the Linux Kernel allows local attackers to elevate privileges.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Time-of-check time-of-use (toctou) race condition in Linux Kernel 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":"Linux Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-62840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Office Graphics Component Information Disclosure Vulnerability","id":"CVE-2026-62842"},"packages":[],"prev":{"headline":"Microsoft SharePoint Server Spoofing Vulnerability","id":"CVE-2026-62839"},"products":["Linux 3P (Third Party) Distros"],"published":"2026-10-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-29","vendors":["Microsoft"]},"summary":"A time-of-check time-of-use race condition in the Linux Kernel allows local attackers to elevate privileges.","url":"https://insights.sbomify.com/CVE-2026-62840/"}
