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-2025-71295 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-2025-71295/ (Markdown: https://insights.sbomify.com/CVE-2025-71295/index.md)","id":"CVE-2025-71295","markdown":"https://insights.sbomify.com/CVE-2025-71295/index.md","name":"CVE-2025-71295","record":{"aliases":["BELL-CVE-2025-71295","DEBIAN-CVE-2025-71295","GHSA-hv9q-ch73-572p","ROOT-OS-DEBIAN-11-CVE-2025-71295","ROOT-OS-UBUNTU-2204-CVE-2025-71295","ROOT-OS-UBUNTU-2404-CVE-2025-71295","UBUNTU-CVE-2025-71295"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A null pointer dereference in the Linux kernel's buffer management can cause a system crash when specific filesystem flags are set without a release operation.","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":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":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfs/buffer: add alert in try_to_free_buffers() for folios without buffers\n\ntry_to_free_buffers() can be called on folios with no buffers attached\nwhen filemap_release_folio() is invoked on a folio belonging to a mapping\nwith AS_RELEASE_ALWAYS set but no release_folio operation defined.\n\nIn such cases, folio_needs_release() returns true because of the\nAS_RELEASE_ALWAYS flag, but the folio has no private buffer data.
