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-2025-38451 in the wild and no public exploit code.\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-2025-38451/ (Markdown: https://insights.sbomify.com/CVE-2025-38451/index.md)","id":"CVE-2025-38451","markdown":"https://insights.sbomify.com/CVE-2025-38451/index.md","name":"CVE-2025-38451","record":{"aliases":["BELL-CVE-2025-38451","DEBIAN-CVE-2025-38451","GHSA-63cx-f5q6-6hg2","ROOT-OS-DEBIAN-12-CVE-2025-38451","UBUNTU-CVE-2025-38451"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can cause a kernel crash by reading bitmap stats, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"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\nmd/md-bitmap: fix GPF in bitmap_get_stats()\n\nThe commit message of commit 6ec1f0239485 (\"md/md-bitmap: fix stats\ncollection for external bitmaps\") states:\n\n    Remove the external bitmap check as the statistics should be\n    available regardless of bitmap storage location.\n\n    Return -EINVAL only for invalid bitmap with no storage (neither in\n    superblock nor in external file).\n\nBut, the code does not adhere to the above, as it does only check for\na valid super-block for \"internal\" bitmaps.
