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-2024-46690 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-2024-46690/ (Markdown: https://insights.sbomify.com/CVE-2024-46690/index.md)","id":"CVE-2024-46690","markdown":"https://insights.sbomify.com/CVE-2024-46690/index.md","name":"CVE-2024-46690","record":{"aliases":["BELL-CVE-2024-46690","DEBIAN-CVE-2024-46690","GHSA-pfgc-2q82-vggq","UBUNTU-CVE-2024-46690"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel NFS","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel NFS server can cause a denial of service when handling third-party leases.","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":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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnfsd: fix nfsd4_deleg_getattr_conflict in presence of third party lease\n\nIt is not safe to dereference fl-\u003ec.flc_owner without first confirming\nfl-\u003efl_lmops is the expected manager.  nfsd4_deleg_getattr_conflict()\ntests fl_lmops but largely ignores the result and assumes that flc_owner\nis an nfs4_delegation anyway.
