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-2026-35358 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- uu_cp (crates.io): affected all versions; fixed in 0.7.0\n- uu_cp (crates.io): affected all versions; fixed in 0.7.0\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-2026-35358/ (Markdown: https://insights.sbomify.com/CVE-2026-35358/index.md)","id":"CVE-2026-35358","markdown":"https://insights.sbomify.com/CVE-2026-35358/index.md","name":"CVE-2026-35358","record":{"aliases":["DEBIAN-CVE-2026-35358","GHSA-8vrf-r662-2w2v","UBUNTU-CVE-2026-35358"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"coreutils utility","requires_auth":"low_privilege","summary":"The cp utility in uutils coreutils causes denial of service by reading device nodes as streams during recursive copies, leading to disk exhaustion or hangs.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"coreutils","vendor":"uutils"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-706","name":"Use of Incorrectly-Resolved Name or Reference"}],"description":"The cp utility in uutils coreutils, when performing recursive copies (-R), incorrectly treats character and block device nodes as stream sources rather than preserving them.
