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-2026-89833 in the wild and no public exploit code.\n\nAffected product: 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-2026-89833/ (Markdown: https://insights.sbomify.com/CVE-2026-89833/index.md)","id":"CVE-2026-89833","markdown":"https://insights.sbomify.com/CVE-2026-89833/index.md","name":"CVE-2026-89833","record":{"aliases":["AZL-101385","BELL-CVE-2026-89833","DEBIAN-CVE-2026-89833","GHSA-fw8r-p3gh-gw7x","UBUNTU-CVE-2026-89833"],"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":"A race condition in the Linux kernel f2fs filesystem can cause a deadloop, leading to denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: fix to avoid potential deadloop in f2fs_fsync_node_pages()\n\nThere is potential deadloop in race condition:\n\nThread A\t\t\t\tThread B\n- fsync\n - f2fs_do_sync_file\n  - f2fs_fsync_node_pages\n   - last_fsync_dnode\n    - folio_get(last_folio)\n\t\t\t\t\t- f2fs_setattr\n\t\t\t\t\t - f2fs_truncate\n\t\t\t\t\t  - f2fs_truncate_blocks\n\t\t\t\t\t   - f2fs_do_truncate_blocks\n\t\t\t\t\t    - f2fs_truncate_inode_blocks\n\t\t\t\t\t     - truncate_dnode\n\t\t\t\t\t      - truncate_node\n\t\t\t\t\t       - invalidate_mapping_pages\n\t\t\t\t\t        - folio-\u003emapping = NULL\n   - is_node_folio alwasy return false\n   - atomic \u0026\u0026 !marked is always true,\n     then goto retry","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":"f2fs: fix to avoid potential deadloop in f2fs_fsync_node_pages()","id":"CVE-2026-89833","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"f2fs: fix to migrate all curseg types during free_segment_range","id":"CVE-2026-89834"},"packages":[],"prev":{"headline":"f2fs: fix to clear dirty flag on folio in error path","id":"CVE-2026-89832"},"products":["Linux"],"published":"2026-09-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Linux"]},"summary":"A race condition in the Linux kernel f2fs filesystem can cause a deadloop, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-89833/"}
