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-2024-44992 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-2024-44992/ (Markdown: https://insights.sbomify.com/CVE-2024-44992/index.md)","id":"CVE-2024-44992","markdown":"https://insights.sbomify.com/CVE-2024-44992/index.md","name":"CVE-2024-44992","record":{"aliases":["BELL-CVE-2024-44992","DEBIAN-CVE-2024-44992","GHSA-53cv-6gxv-7335","UBUNTU-CVE-2024-44992"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel SMB client 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":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb/client: avoid possible NULL dereference in cifs_free_subrequest()\n\nClang static checker (scan-build) warning:\n\tcifsglob.h:line 890, column 3\n\tAccess to field 'ops' results in a dereference of a null pointer.\n\nCommit 519be989717c (\"cifs: Add a tracepoint to track credits involved in\nR/W requests\") adds a check for 'rdata-\u003eserver', and let clang throw this\nwarning about NULL dereference.\n\nWhen 'rdata-\u003ecredits.value != 0 \u0026\u0026 rdata-\u003eserver == NULL' happens,\nadd_credits_and_wake_if() will call rdata-\u003eserver-\u003eops-\u003eadd_credits().\nThis will cause NULL dereference problem.
