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-2025-38724 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2025-38724/ (Markdown: https://insights.sbomify.com/CVE-2025-38724/index.md)","id":"CVE-2025-38724","markdown":"https://insights.sbomify.com/CVE-2025-38724/index.md","name":"CVE-2025-38724","record":{"aliases":["AZL-66854","AZL-73839","BELL-CVE-2025-38724","DEBIAN-CVE-2025-38724","GHSA-x8r2-g34h-2v3j","ROOT-OS-DEBIAN-11-CVE-2025-38724","ROOT-OS-DEBIAN-12-CVE-2025-38724","ROOT-OS-UBUNTU-2204-CVE-2025-38724","ROOT-OS-UBUNTU-2404-CVE-2025-38724","UBUNTU-CVE-2025-38724"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel NFS","requires_auth":"none","summary":"A race condition in the Linux kernel NFS server allows attackers to trigger a use-after-free, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm()\n\nLei Lu recently reported that nfsd4_setclientid_confirm() did not check\nthe return value from get_client_locked(). a SETCLIENTID_CONFIRM could\nrace with a confirmed client expiring and fail to get a reference.
