An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-56749 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-2024-56749/ (Markdown: https://insights.sbomify.com/CVE-2024-56749/index.md)","id":"CVE-2024-56749","markdown":"https://insights.sbomify.com/CVE-2024-56749/index.md","name":"CVE-2024-56749","record":{"aliases":["BELL-CVE-2024-56749","DEBIAN-CVE-2024-56749","GHSA-9r43-p7wr-7396","UBUNTU-CVE-2024-56749"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel DLM","requires_auth":"none","summary":"A refcount leak in the Linux kernel Distributed Lock Manager can cause resource exhaustion and denial of service during recovery failures.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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\ndlm: fix dlm_recover_members refcount on error\n\nIf dlm_recover_members() fails we don't drop the references of the\nprevious created root_list that holds and keep all rsbs alive during the\nrecovery.
