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-2025-68791 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-2025-68791/ (Markdown: https://insights.sbomify.com/CVE-2025-68791/index.md)","id":"CVE-2025-68791","markdown":"https://insights.sbomify.com/CVE-2025-68791/index.md","name":"CVE-2025-68791","record":{"aliases":["BELL-CVE-2025-68791","DEBIAN-CVE-2025-68791","GHSA-7jvc-cm4g-4hr3","UBUNTU-CVE-2025-68791"],"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 missing copy_finish in fuse-over-io-uring causes a reference count leak, potentially leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nfuse: missing copy_finish in fuse-over-io-uring argument copies\n\nFix a possible reference count leak of payload pages during\nfuse argument copies.\n\n[Joanne: simplified error cleanup]","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":"fuse: missing copy_finish in fuse-over-io-uring argument copies","id":"CVE-2025-68791","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"tpm2-sessions: Fix out of range indexing in name_size","id":"CVE-2025-68792"},"packages":[],"prev":{"headline":"net/mlx5: Fix double unregister of HCA_PORTS component","id":"CVE-2025-68790"},"products":["Linux"],"published":"2026-01-13","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":"2026-05-11","vendors":["Linux"]},"summary":"A missing copy_finish in fuse-over-io-uring causes a reference count leak, potentially leading to denial of service.","url":"https://insights.sbomify.com/CVE-2025-68791/"}
