It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2018-8405 in the wild since at least 28 Mar 2022, including in ransomware campaigns.\n\nAffected product: Microsoft Windows 10 1507. 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-2018-8405/ (Markdown: https://insights.sbomify.com/CVE-2018-8405/index.md)","id":"CVE-2018-8405","markdown":"https://insights.sbomify.com/CVE-2018-8405/index.md","name":"CVE-2018-8405","record":{"aliases":["GHSA-87h6-m3qc-h3rx"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows OS","requires_auth":"low_privilege","summary":"An attacker can exploit improper memory handling in the DirectX Graphics Kernel driver to elevate privileges on affected Windows systems.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1507","vendor":"microsoft"},{"product":"windows_10_1607","vendor":"microsoft"},{"product":"windows_10_1703","vendor":"microsoft"},{"product":"windows_10_1709","vendor":"microsoft"},{"product":"windows_10_1803","vendor":"microsoft"},{"product":"windows_8.1","vendor":"microsoft"},{"product":"windows_rt_8.1","vendor":"microsoft"},{"product":"windows_server_1709","vendor":"microsoft"},{"product":"windows_server_1803","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"An elevation of privilege vulnerability exists when the DirectX Graphics Kernel (DXGKRNL) driver improperly handles objects in memory, aka \"DirectX Graphics Kernel Elevation of Privilege Vulnerability.\" This affects Windows Server 2012 R2, Windows RT 8.1, Windows Server 2016, Windows 8.1, Windows 10, Windows 10 Servers.
