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-2021-33098 in the wild and no public exploit code.\n\nAffected product: Intel(R) Ethernet ixgbe driver for 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-2021-33098/ (Markdown: https://insights.sbomify.com/CVE-2021-33098/index.md)","id":"CVE-2021-33098","markdown":"https://insights.sbomify.com/CVE-2021-33098/index.md","name":"CVE-2021-33098","record":{"aliases":["DEBIAN-CVE-2021-33098","GHSA-m2q2-cqf3-9j32","OESA-2021-1465","UBUNTU-CVE-2021-33098"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux network driver","requires_auth":"low_privilege","summary":"An authenticated local user can cause a denial of service in the Intel ixgbe Linux driver due to improper input validation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[{"product":"ethernet_500_series_controllers_driver","vendor":"intel"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may allow an authenticated user to potentially enable denial of service via local access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in Intel(R) Ethernet ixgbe driver for Linux","id":"CVE-2021-33098","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"This is unused.","id":"CVE-2021-33099"},"packages":[],"prev":{"headline":"Race condition in Intel(R) SGX","id":"CVE-2021-33097"},"products":["Intel(R) Ethernet ixgbe driver for Linux"],"published":"2021-11-17","related":[],"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":["n/a"]},"summary":"An authenticated local user can cause a denial of service in the Intel ixgbe Linux driver due to improper input validation.","url":"https://insights.sbomify.com/CVE-2021-33098/"}
