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-2021-1117 in the wild and no public exploit code.\n\nAffected product: Nvidia Gpu Display Driver. 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-2021-1117/ (Markdown: https://insights.sbomify.com/CVE-2021-1117/index.md)","id":"CVE-2021-1117","markdown":"https://insights.sbomify.com/CVE-2021-1117/index.md","name":"CVE-2021-1117","record":{"aliases":["GHSA-c663-86cm-fc8f"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"NVIDIA GPU Driver","requires_auth":"low_privilege","summary":"Local attackers can cause denial of service in NVIDIA GPU drivers via improper input validation in the kernel mode layer.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"nvidia","cpe":[{"product":"gpu_display_driver","vendor":"nvidia"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"Windows contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape, where an attacker through specific configuration and with local unprivileged system access may cause improper input validation, which may lead to denial of service.","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":"Denial of service in NVIDIA GPU Display Driver","id":"CVE-2021-1117","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nvidia:gpu_display_driver","products":["nvidia:gpu_display_driver"],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in NVIDIA Virtual GPU Software","id":"CVE-2021-1118"},"packages":[],"prev":{"headline":"Null dereference in NVIDIA GPU Display Driver","id":"CVE-2021-1116"},"products":["NVIDIA GPU Display Driver"],"published":"2021-10-27","related":[{"cvss_score":8.8,"headline":"Use after free in GeForce","id":"CVE-2026-24187","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":8.8,"headline":"Privilege escalation in NVIDIA GPU Display Driver","id":"CVE-2023-0184","kev_date_added":null,"published":"2023-04-22"},{"cvss_score":8.5,"headline":"Memory corruption in NVIDIA GPU Display Driver for Windows","id":"CVE-2022-34671","kev_date_added":null,"published":"2022-12-30"},{"cvss_score":8.5,"headline":"Memory corruption in NVIDIA GPU Display Driver","id":"CVE-2022-28181","kev_date_added":null,"published":"2022-05-17"},{"cvss_score":8.5,"headline":"Memory corruption in NVIDIA GPU Display Driver","id":"CVE-2022-28182","kev_date_added":null,"published":"2022-05-17"},{"cvss_score":7.8,"headline":"Privilege escalation in GeForce","id":"CVE-2026-24190","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":7.8,"headline":"Race condition in GeForce","id":"CVE-2026-24191","kev_date_added":null,"published":"2026-05-26"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["NVIDIA"]},"summary":"Local attackers can cause denial of service in NVIDIA GPU drivers via improper input validation in the kernel mode layer.","url":"https://insights.sbomify.com/CVE-2021-1117/"}
