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-2026-80898 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-2026-80898/ (Markdown: https://insights.sbomify.com/CVE-2026-80898/index.md)","id":"CVE-2026-80898","markdown":"https://insights.sbomify.com/CVE-2026-80898/index.md","name":"CVE-2026-80898","record":{"aliases":["BELL-CVE-2026-80898","DEBIAN-CVE-2026-80898","GHSA-rr37-5j55-39mh","UBUNTU-CVE-2026-80898"],"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":"none","summary":"A bug in the Linux kernel netfs module fails to clear a page flag on append failure, potentially leading to resource leaks or denial of service.","user_interaction":"not_required","vuln_class":"other"},"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\nnetfs: clear PG_private_2 on copy-to-cache append failure\n\nnetfs_pgpriv2_copy_to_cache() marks the folio with PG_private_2 before\nnetfs_pgpriv2_copy_folio() appends it to the copy-to-cache rolling\nbuffer.\n\nIf the append fails, the folio is not queued for cache writeback, so\nthe PG_private_2 state and its reference must be released immediately.","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":"netfs: clear PG_private_2 on copy-to-cache append failure","id":"CVE-2026-80898","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"erofs: remove fscache backend entirely","id":"CVE-2026-80899"},"packages":[],"prev":{"headline":"netfs: release readahead folios on iterator preparation failure","id":"CVE-2026-80897"},"products":["Linux"],"published":"2026-09-04","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":"2026-09-04","vendors":["Linux"]},"summary":"A bug in the Linux kernel netfs module fails to clear a page flag on append failure, potentially leading to resource leaks or denial of service.","url":"https://insights.sbomify.com/CVE-2026-80898/"}
