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-2025-39975 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-2025-39975/ (Markdown: https://insights.sbomify.com/CVE-2025-39975/index.md)","id":"CVE-2025-39975","markdown":"https://insights.sbomify.com/CVE-2025-39975/index.md","name":"CVE-2025-39975","record":{"aliases":["BELL-CVE-2025-39975","DEBIAN-CVE-2025-39975","GHSA-cm9p-f4x4-35gj","ROOT-OS-DEBIAN-13-CVE-2025-39975","UBUNTU-CVE-2025-39975"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"none","summary":"A wrong index reference in the Linux kernel SMB client can cause out-of-bounds memory accesses, potentially leading to code execution or system crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: fix wrong index reference in smb2_compound_op()\n\nIn smb2_compound_op(), the loop that processes each command's response\nuses wrong indices when accessing response bufferes.\n\nThis incorrect indexing leads to improper handling of command results.\nAlso, if incorrectly computed index is greather than or equal to\nMAX_COMPOUND, it can cause out-of-bounds accesses.","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 wrong index reference in smb2_compound_op()","id":"CVE-2025-39975","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"futex: Use correct exit on failure from futex_hash_allocate_default()","id":"CVE-2025-39976"},"packages":[],"prev":{"headline":"tracing/osnoise: Fix slab-out-of-bounds in _parse_integer_limit()","id":"CVE-2025-39974"},"products":["Linux"],"published":"2025-10-15","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A wrong index reference in the Linux kernel SMB client can cause out-of-bounds memory accesses, potentially leading to code execution or system crashes.","url":"https://insights.sbomify.com/CVE-2025-39975/"}
