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-2025-38561 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-2025-38561/ (Markdown: https://insights.sbomify.com/CVE-2025-38561/index.md)","id":"CVE-2025-38561","markdown":"https://insights.sbomify.com/CVE-2025-38561/index.md","name":"CVE-2025-38561","record":{"aliases":["BELL-CVE-2025-38561","DEBIAN-CVE-2025-38561","GHSA-6mwh-579p-fgpg","ROOT-OS-DEBIAN-11-CVE-2025-38561","ROOT-OS-DEBIAN-12-CVE-2025-38561","ROOT-OS-DEBIAN-13-CVE-2025-38561","ROOT-OS-UBUNTU-2204-CVE-2025-38561","ROOT-OS-UBUNTU-2404-CVE-2025-38561"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A race condition in the Linux kernel's ksmbd module allows attackers to cause a denial of service via multiple session setup requests.","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":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":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: fix Preauh_HashValue race condition\n\nIf client send multiple session setup requests to ksmbd,\nPreauh_HashValue race condition could happen.\nThere is no need to free sess-\u003ePreauh_HashValue at session setup phase.\nIt can be freed together with session at connection termination phase.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-10-08","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-10-08T18:20:08Z","kind":"github_poc","ref":"https://github.com/toshithh/CVE-2025-38561","stars":0,"title":" ksmbd: Preauh_HashValue race condition If client send multiple session setup requests to ksmbd, Preauh_HashValue race condition could happen."}],"tier":"poc_unverified"},"has_fix":true,"headline":"ksmbd: fix Preauh_HashValue race condition","id":"CVE-2025-38561","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":"ksmbd: fix null pointer dereference error in generate_encryptionkey","id":"CVE-2025-38562"},"packages":[],"prev":{"headline":"x86/sev: Evict cache lines during SNP memory validation","id":"CVE-2025-38560"},"products":["Linux"],"published":"2025-08-19","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A race condition in the Linux kernel's ksmbd module allows attackers to cause a denial of service via multiple session setup requests.","url":"https://insights.sbomify.com/CVE-2025-38561/"}
