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-2025-38393 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-2025-38393/ (Markdown: https://insights.sbomify.com/CVE-2025-38393/index.md)","id":"CVE-2025-38393","markdown":"https://insights.sbomify.com/CVE-2025-38393/index.md","name":"CVE-2025-38393","record":{"aliases":["AZL-65717","AZL-73010","BELL-CVE-2025-38393","DEBIAN-CVE-2025-38393","GHSA-93f5-rwwh-v8p5","ROOT-OS-DEBIAN-11-CVE-2025-38393","ROOT-OS-DEBIAN-12-CVE-2025-38393","ROOT-OS-UBUNTU-2204-CVE-2025-38393","ROOT-OS-UBUNTU-2404-CVE-2025-38393","UBUNTU-CVE-2025-38393"],"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 race condition in the Linux kernel's NFSv4/pNFS implementation can cause system hangs during writeback operations, leading to denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"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":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nNFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN\n\nWe found a few different systems hung up in writeback waiting on the same\npage lock, and one task waiting on the NFS_LAYOUT_DRAIN bit in\npnfs_update_layout(), however the pnfs_layout_hdr's plh_outstanding count\nwas zero.\n\nIt seems most likely that this is another race between the waiter and waker\nsimilar to commit ed0172af5d6f (\"SUNRPC: Fix a race to wake a sync task\").\nFix it up by applying the advised barrier.","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":"NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN","id":"CVE-2025-38393","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","linux:linux_kernel"],"type":"race_condition","year":"2025"},"n_packages":0,"n_references":7,"next":{"headline":"HID: appletb-kbd: fix memory corruption of input_handler_list","id":"CVE-2025-38394"},"packages":[],"prev":{"headline":"idpf: convert control queue mutex to a spinlock","id":"CVE-2025-38392"},"products":["Linux"],"published":"2025-07-25","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A race condition in the Linux kernel's NFSv4/pNFS implementation can cause system hangs during writeback operations, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2025-38393/"}
