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-2025-38711 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-2025-38711/ (Markdown: https://insights.sbomify.com/CVE-2025-38711/index.md)","id":"CVE-2025-38711","markdown":"https://insights.sbomify.com/CVE-2025-38711/index.md","name":"CVE-2025-38711","record":{"aliases":["AZL-66872","BELL-CVE-2025-38711","DEBIAN-CVE-2025-38711","GHSA-c3j4-c39c-w5r2","ROOT-OS-DEBIAN-11-CVE-2025-38711","ROOT-OS-DEBIAN-12-CVE-2025-38711","ROOT-OS-UBUNTU-2204-CVE-2025-38711","ROOT-OS-UBUNTU-2404-CVE-2025-38711","UBUNTU-CVE-2025-38711"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel SMB server","requires_auth":"low_privilege","summary":"A deadlock in the Linux kernel SMB server allows remote attackers to cause a denial of service by triggering a specific file linking operation.","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":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb/server: avoid deadlock when linking with ReplaceIfExists\n\nIf smb2_create_link() is called with ReplaceIfExists set and the name\ndoes exist then a deadlock will happen.\n\nksmbd_vfs_kern_path_locked() will return with success and the parent\ndirectory will be locked.  ksmbd_vfs_remove_file() will then remove the\nfile.  ksmbd_vfs_link() will then be called while the parent is still\nlocked.
