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-2025-40267 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-2025-40267/ (Markdown: https://insights.sbomify.com/CVE-2025-40267/index.md)","id":"CVE-2025-40267","markdown":"https://insights.sbomify.com/CVE-2025-40267/index.md","name":"CVE-2025-40267","record":{"aliases":["BELL-CVE-2025-40267","DEBIAN-CVE-2025-40267","GHSA-3qj7-2xc7-mxqw","UBUNTU-CVE-2025-40267"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can trigger a memory leak in the Linux kernel's io_uring subsystem, potentially leading to denial of service or information disclosure.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nio_uring/rw: ensure allocated iovec gets cleared for early failure\n\nA previous commit reused the recyling infrastructure for early cleanup,\nbut this is not enough for the case where our internal caches have\noverflowed.
