Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-64519 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-2026-64519/ (Markdown: https://insights.sbomify.com/CVE-2026-64519/index.md)","id":"CVE-2026-64519","markdown":"https://insights.sbomify.com/CVE-2026-64519/index.md","name":"CVE-2026-64519","record":{"aliases":["BELL-CVE-2026-64519","DEBIAN-CVE-2026-64519","GHSA-gv69-m9qg-32px","ROOT-OS-UBUNTU-2204-CVE-2026-64519","UBUNTU-CVE-2026-64519"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An attacker can cause a denial of service in the Linux kernel's NFSD by triggering an infinite loop during layout state revocation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nNFSD: Fix infinite loop in layout state revocation\n\nfind_one_sb_stid() skips stids whose sc_status is non-zero, but the\nSC_TYPE_LAYOUT case in nfsd4_revoke_states() never sets sc_status\nbefore calling nfsd4_close_layout().
