It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-37833 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-2025-37833/ (Markdown: https://insights.sbomify.com/CVE-2025-37833/index.md)","id":"CVE-2025-37833","markdown":"https://insights.sbomify.com/CVE-2025-37833/index.md","name":"CVE-2025-37833","record":{"aliases":["BELL-CVE-2025-37833","DEBIAN-CVE-2025-37833","GHSA-3vhw-gffp-6qr6","ROOT-OS-DEBIAN-11-CVE-2025-37833","ROOT-OS-DEBIAN-12-CVE-2025-37833","ROOT-OS-UBUNTU-2204-CVE-2025-37833","ROOT-OS-UBUNTU-2404-CVE-2025-37833","UBUNTU-CVE-2025-37833"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel network driver","requires_auth":"low_privilege","summary":"A bug in the Linux kernel's niu network driver causes a fatal system trap on SPARC systems during initialization, leading to a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/niu: Niu requires MSIX ENTRY_DATA fields touch before entry reads\n\nFix niu_try_msix() to not cause a fatal trap on sparc systems.\n\nSet PCI_DEV_FLAGS_MSIX_TOUCH_ENTRY_DATA_FIRST on the struct pci_dev to\nwork around a bug in the hardware or firmware.\n\nFor each vector entry in the msix table, niu chips will cause a fatal\ntrap if any registers in that entry are read before that entries'\nENTRY_DATA register is written to.
