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-2025-39800 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-2025-39800/ (Markdown: https://insights.sbomify.com/CVE-2025-39800/index.md)","id":"CVE-2025-39800","markdown":"https://insights.sbomify.com/CVE-2025-39800/index.md","name":"CVE-2025-39800","record":{"aliases":["BELL-CVE-2025-39800","DEBIAN-CVE-2025-39800","GHSA-q638-mxxh-qchw","ROOT-OS-DEBIAN-11-CVE-2025-39800","ROOT-OS-UBUNTU-2204-CVE-2025-39800","ROOT-OS-UBUNTU-2404-CVE-2025-39800","UBUNTU-CVE-2025-39800"],"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 flaw in the Linux kernel's btrfs filesystem allows persisting invalid metadata, potentially leading to system instability or denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: abort transaction on unexpected eb generation at btrfs_copy_root()\n\nIf we find an unexpected generation for the extent buffer we are cloning\nat btrfs_copy_root(), we just WARN_ON() and don't error out and abort the\ntransaction, meaning we allow to persist metadata with an unexpected\ngeneration.
