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-2025-40101 in the wild and no public exploit code.\n\nAffected product: 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-2025-40101/ (Markdown: https://insights.sbomify.com/CVE-2025-40101/index.md)","id":"CVE-2025-40101","markdown":"https://insights.sbomify.com/CVE-2025-40101/index.md","name":"CVE-2025-40101","record":{"aliases":["BELL-CVE-2025-40101","DEBIAN-CVE-2025-40101","GHSA-qqwh-7pmj-9xx8","ROOT-OS-DEBIAN-13-CVE-2025-40101","ROOT-OS-UBUNTU-2404-CVE-2025-40101","UBUNTU-CVE-2025-40101"],"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":"none","summary":"A memory leak in the Linux kernel btrfs filesystem allows local attackers to cause denial of service by exhausting system memory.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: fix memory leaks when rejecting a non SINGLE data profile without an RST\n\nAt the end of btrfs_load_block_group_zone_info() the first thing we do\nis to ensure that if the mapping type is not a SINGLE one and there is\nno RAID stripe tree, then we return early with an error.\n\nDoing that, though, prevents the code from running the last calls from\nthis function which are about freeing memory allocated during its\nrun.
