Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-37947 exists.\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-2025-37947/ (Markdown: https://insights.sbomify.com/CVE-2025-37947/index.md)","id":"CVE-2025-37947","markdown":"https://insights.sbomify.com/CVE-2025-37947/index.md","name":"CVE-2025-37947","record":{"aliases":["BELL-CVE-2025-37947","DEBIAN-CVE-2025-37947","GHSA-c42x-xw5m-9j9p","ROOT-OS-DEBIAN-12-CVE-2025-37947","ROOT-OS-UBUNTU-2204-CVE-2025-37947","ROOT-OS-UBUNTU-2404-CVE-2025-37947","UBUNTU-CVE-2025-37947"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An out-of-bounds write in the ksmbd kernel module allows attackers to potentially execute code or escalate privileges via crafted stream write requests.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: prevent out-of-bounds stream writes by validating *pos\n\nksmbd_vfs_stream_write() did not validate whether the write offset\n(*pos) was within the bounds of the existing stream data length (v_len).\nIf *pos was greater than or equal to v_len, this could lead to an\nout-of-bounds memory write.\n\nThis patch adds a check to ensure *pos is less than v_len before\nproceeding.
