It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-39825 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-2025-39825/ (Markdown: https://insights.sbomify.com/CVE-2025-39825/index.md)","id":"CVE-2025-39825","markdown":"https://insights.sbomify.com/CVE-2025-39825/index.md","name":"CVE-2025-39825","record":{"aliases":["AZL-67386","BELL-CVE-2025-39825","DEBIAN-CVE-2025-39825","GHSA-3f3q-q5cj-phc5","ROOT-OS-DEBIAN-11-CVE-2025-39825","ROOT-OS-DEBIAN-12-CVE-2025-39825","ROOT-OS-DEBIAN-13-CVE-2025-39825","ROOT-OS-UBUNTU-2204-CVE-2025-39825","ROOT-OS-UBUNTU-2404-CVE-2025-39825","UBUNTU-CVE-2025-39825"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel SMB client during rename operations allows concurrent opens, potentially leading to inconsistent file states.","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":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/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\nsmb: client: fix race with concurrent opens in rename(2)\n\nBesides sending the rename request to the server, the rename process\nalso involves closing any deferred close, waiting for outstanding I/O\nto complete as well as marking all existing open handles as deleted to\nprevent them from deferring closes, which increases the race window\nfor potential concurrent opens on the target file.\n\nFix this by unhashing the dentry in advance to prevent any concurrent\nopens on the target.","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":"smb: client: fix race with concurrent opens in rename(2)","id":"CVE-2025-39825","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":5,"next":{"headline":"net: rose: convert 'use' field to refcount_t","id":"CVE-2025-39826"},"packages":[],"prev":{"headline":"HID: asus: fix UAF via HID_CLAIMED_INPUT validation","id":"CVE-2025-39824"},"products":["Linux"],"published":"2025-09-16","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A race condition in the Linux kernel SMB client during rename operations allows concurrent opens, potentially leading to inconsistent file states.","url":"https://insights.sbomify.com/CVE-2025-39825/"}
