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-2025-40324 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-2025-40324/ (Markdown: https://insights.sbomify.com/CVE-2025-40324/index.md)","id":"CVE-2025-40324","markdown":"https://insights.sbomify.com/CVE-2025-40324/index.md","name":"CVE-2025-40324","record":{"aliases":["BELL-CVE-2025-40324","DEBIAN-CVE-2025-40324","GHSA-cfr4-frvg-x3c3","ROOT-OS-DEBIAN-12-CVE-2025-40324","ROOT-OS-DEBIAN-13-CVE-2025-40324","ROOT-OS-UBUNTU-2204-CVE-2025-40324","ROOT-OS-UBUNTU-2404-CVE-2025-40324","UBUNTU-CVE-2025-40324"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux kernel NFSD","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel NFSD module causes a crash when tracing is enabled during specific NFS read operations.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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\nNFSD: Fix crash in nfsd4_read_release()\n\nWhen tracing is enabled, the trace_nfsd_read_done trace point\ncrashes during the pynfs read.testNoFh test.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"NFSD: Fix crash in nfsd4_read_release()","id":"CVE-2025-40324","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":7,"next":{"headline":"md/raid10: wait barrier before returning discard request with REQ_NOWAIT","id":"CVE-2025-40325"},"packages":[],"prev":{"headline":"fbcon: Set fb_display[i]-\u003emode to NULL when the mode is released","id":"CVE-2025-40323"},"products":["Linux"],"published":"2025-12-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel NFSD module causes a crash when tracing is enabled during specific NFS read operations.","url":"https://insights.sbomify.com/CVE-2025-40324/"}
