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-2025-71086 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2025-71086/ (Markdown: https://insights.sbomify.com/CVE-2025-71086/index.md)","id":"CVE-2025-71086","markdown":"https://insights.sbomify.com/CVE-2025-71086/index.md","name":"CVE-2025-71086","record":{"aliases":["BELL-CVE-2025-71086","DEBIAN-CVE-2025-71086","GHSA-mqvv-vjpm-cprh","ROOT-OS-DEBIAN-11-CVE-2025-71086","ROOT-OS-DEBIAN-12-CVE-2025-71086","ROOT-OS-DEBIAN-13-CVE-2025-71086","ROOT-OS-UBUNTU-2204-CVE-2025-71086","ROOT-OS-UBUNTU-2404-CVE-2025-71086","UBUNTU-CVE-2025-71086"],"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":"An invalid array index in the Linux kernel's ROSE network module can cause a null pointer dereference and reference leak, leading to a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: rose: fix invalid array index in rose_kill_by_device()\n\nrose_kill_by_device() collects sockets into a local array[] and then\niterates over them to disconnect sockets bound to a device being brought\ndown.\n\nThe loop mistakenly indexes array[cnt] instead of array[i].
