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-2026-74730 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-2026-74730/ (Markdown: https://insights.sbomify.com/CVE-2026-74730/index.md)","id":"CVE-2026-74730","markdown":"https://insights.sbomify.com/CVE-2026-74730/index.md","name":"CVE-2026-74730","record":{"aliases":["AZL-97275","BELL-CVE-2026-74730","DEBIAN-CVE-2026-74730","GHSA-rmc7-77jw-fvm4","UBUNTU-CVE-2026-74730"],"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 use-after-free vulnerability in the Linux kernel's NFS implementation allows attackers to potentially execute code or escalate privileges via delayed FREE_STATEID operations.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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\nNFS: Pin the 'struct nfs_server' during a FREE_STATEID call\n\nDan Aloni reports that he was able to hit a use-after-free bug if a\nFREE_STATEID operation gets delayed for whatever reason.
