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-2025-38737 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2025-38737/ (Markdown: https://insights.sbomify.com/CVE-2025-38737/index.md)","id":"CVE-2025-38737","markdown":"https://insights.sbomify.com/CVE-2025-38737/index.md","name":"CVE-2025-38737","record":{"aliases":["BELL-CVE-2025-38737","DEBIAN-CVE-2025-38737","GHSA-86v2-3hvm-7hww","RHSA-2025:23009","ROOT-OS-DEBIAN-13-CVE-2025-38737","UBUNTU-CVE-2025-38737"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel CIFS","requires_auth":"none","summary":"An uninitialized variable in the Linux kernel CIFS module can cause a system crash, requiring a kernel patch to prevent denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"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-908","name":"Use of Uninitialized Resource"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncifs: Fix oops due to uninitialised variable\n\nFix smb3_init_transform_rq() to initialise buffer to NULL before calling\nnetfs_alloc_folioq_buffer() as netfs assumes it can append to the buffer it\nis given.
