It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-58600 and fix it if it is affected.\n\nWhat it is: CVE-2026-58600 is a high-severity memory corruption vulnerability in Microsoft HEVC Video Extensions, published on 8 Sep 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-58600 in the wild and no public exploit code.\n\nAffected product: Microsoft HEVC Video Extensions. 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-2026-58600/ (Markdown: https://insights.sbomify.com/CVE-2026-58600/index.md)","id":"CVE-2026-58600","markdown":"https://insights.sbomify.com/CVE-2026-58600/index.md","name":"CVE-2026-58600","record":{"aliases":["GHSA-j9hq-499p-g5xg"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows HEVC Codec","requires_auth":"none","summary":"A heap-based buffer overflow in the Windows HEVC Video Extensions allows local attackers to elevate privileges.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"hevc_video_extensions","vendor":"microsoft"},{"product":"hevc_video_extensions_for_licensed_applications","vendor":"microsoft"},{"product":"hevc_video_extensions_from_device_manufacturer","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/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 Microsoft Windows Codecs Library allows an unauthorized 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":"HEVC Video Extensions Elevation of Privilege Vulnerability","id":"CVE-2026-58600","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":"Virtual Hard Disk (VHD) Miniport Driver Elevation of Privilege Vulernability","id":"CVE-2026-58601"},"packages":[],"prev":{"headline":"HEVC Video Extensions Remote Code Execution Vulnerability","id":"CVE-2026-58599"},"products":["HEVC Video Extensions","HEVC Video Extensions for Licensed Applications","HEVC Video Extensions from Device Manufacturer"],"published":"2026-09-08","related":[{"cvss_score":7.8,"headline":"HEVC Video Extensions Remote Code Execution Vulnerability","id":"CVE-2026-58599","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":7.8,"headline":"HEVC Video Extensions Remote Code Execution Vulnerability","id":"CVE-2023-38170","kev_date_added":null,"published":"2023-08-08"},{"cvss_score":7.8,"headline":"HEVC Video Extensions Remote Code Execution Vulnerability","id":"CVE-2022-22018","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":7.8,"headline":"HEVC Video Extensions Remote Code Execution Vulnerability","id":"CVE-2022-29111","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":7.8,"headline":"HEVC Video Extensions Remote Code Execution Vulnerability","id":"CVE-2022-29119","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":7.8,"headline":"HEVC Video Extensions Remote Code Execution Vulnerability","id":"CVE-2022-30188","kev_date_added":null,"published":"2022-06-15"}],"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 HEVC Video Extensions allows local attackers to elevate privileges.","url":"https://insights.sbomify.com/CVE-2026-58600/"}
