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-2024-47739 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-2024-47739/ (Markdown: https://insights.sbomify.com/CVE-2024-47739/index.md)","id":"CVE-2024-47739","markdown":"https://insights.sbomify.com/CVE-2024-47739/index.md","name":"CVE-2024-47739","record":{"aliases":["AZL-50809","AZL-50996","BELL-CVE-2024-47739","DEBIAN-CVE-2024-47739","GHSA-c5xm-9r44-7w3j","UBUNTU-CVE-2024-47739"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An integer overflow in the Linux kernel padata subsystem can cause a deadlock, leading to a denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"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":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\npadata: use integer wrap around to prevent deadlock on seq_nr overflow\n\nWhen submitting more than 2^32 padata objects to padata_do_serial, the\ncurrent sorting implementation incorrectly sorts padata objects with\noverflowed seq_nr, causing them to be placed before existing objects in\nthe reorder list.
