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-2021-1056 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2021-1056/ (Markdown: https://insights.sbomify.com/CVE-2021-1056/index.md)","id":"CVE-2021-1056","markdown":"https://insights.sbomify.com/CVE-2021-1056/index.md","name":"CVE-2021-1056","record":{"aliases":["DEBIAN-CVE-2021-1056","GHSA-f8fj-4gwg-crcc","UBUNTU-CVE-2021-1056"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NVIDIA GPU Driver","requires_auth":"low_privilege","summary":"NVIDIA GPU driver fails to enforce file system permissions, allowing local attackers to cause denial of service or disclose information.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"nvidia","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"gpu_driver","vendor":"nvidia"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"NVIDIA GPU Display Driver for Linux, all versions, contains a vulnerability in the kernel mode layer (nvidia.ko) in which it does not completely honor operating system file system permissions to provide GPU device-level isolation, which may lead to denial of service or information disclosure.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-01-08","github_poc":1,"max_poc_stars":16,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-01-08T11:29:48Z","kind":"github_poc","ref":"https://github.com/pokerfaceSad/CVE-2021-1056","stars":16,"title":"PoC for CVE-2021-1056, related to GPU Container Security"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Missing authorization in NVIDIA GPU Display Driver","id":"CVE-2021-1056","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","nvidia:gpu_driver"],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Privilege escalation in NVIDIA Virtual GPU Manager","id":"CVE-2021-1057"},"packages":[],"prev":{"headline":"Information disclosure in NVIDIA GPU Display Driver","id":"CVE-2021-1055"},"products":["NVIDIA GPU Display Driver"],"published":"2021-01-08","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["NVIDIA"]},"summary":"NVIDIA GPU driver fails to enforce file system permissions, allowing local attackers to cause denial of service or disclose information.","url":"https://insights.sbomify.com/CVE-2021-1056/"}
