An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-71150 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-2025-71150/ (Markdown: https://insights.sbomify.com/CVE-2025-71150/index.md)","id":"CVE-2025-71150","markdown":"https://insights.sbomify.com/CVE-2025-71150/index.md","name":"CVE-2025-71150","record":{"aliases":["AZL-78425","BELL-CVE-2025-71150","DEBIAN-CVE-2025-71150","GHSA-4mf3-frrh-jfqw","ROOT-OS-DEBIAN-12-CVE-2025-71150","ROOT-OS-DEBIAN-13-CVE-2025-71150","ROOT-OS-UBUNTU-2204-CVE-2025-71150","ROOT-OS-UBUNTU-2404-CVE-2025-71150","UBUNTU-CVE-2025-71150"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A reference count leak in the Linux kernel's ksmbd module can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: Fix refcount leak when invalid session is found on session lookup\n\nWhen a session is found but its state is not SMB2_SESSION_VALID, It\nindicates that no valid session was found, but it is missing to decrement\nthe reference count acquired by the session lookup, which results in\na reference count leak.
