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-2021-33631 in the wild and no public exploit code.\n\nAffected product: openEuler kernel. 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-2021-33631/ (Markdown: https://insights.sbomify.com/CVE-2021-33631/index.md)","id":"CVE-2021-33631","markdown":"https://insights.sbomify.com/CVE-2021-33631/index.md","name":"CVE-2021-33631","record":{"aliases":["DEBIAN-CVE-2021-33631","GHSA-ff22-5jp8-224r","UBUNTU-CVE-2021-33631"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An integer overflow in the EXT4 filesystem module allows attackers to cause a kernel crash, resulting in denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openEuler","cpe":[{"product":"openeuler","vendor":"openatom"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","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-190","name":"Integer Overflow or Wraparound"}],"description":"Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from 5.10.0-60.18.0 before 5.10.0-183.0.0.","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":"Kernel crash in EXT4 filesystem","id":"CVE-2021-33631","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2021"},"n_packages":0,"n_references":19,"next":{"headline":"TOCTOU Race Condition problem in iSulad","id":"CVE-2021-33632"},"packages":[],"prev":{"headline":"NULL-ptr-deref in network sched","id":"CVE-2021-33630"},"products":["kernel"],"published":"2024-01-18","related":[{"cvss_score":5.5,"headline":"NULL-ptr-deref in network sched","id":"CVE-2021-33630","kev_date_added":null,"published":"2024-01-18"}],"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":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["openEuler"]},"summary":"An integer overflow in the EXT4 filesystem module allows attackers to cause a kernel crash, resulting in denial of service.","url":"https://insights.sbomify.com/CVE-2021-33631/"}
