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-2025-38161 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-2025-38161/ (Markdown: https://insights.sbomify.com/CVE-2025-38161/index.md)","id":"CVE-2025-38161","markdown":"https://insights.sbomify.com/CVE-2025-38161/index.md","name":"CVE-2025-38161","record":{"aliases":["AZL-64490","BELL-CVE-2025-38161","DEBIAN-CVE-2025-38161","GHSA-hc4c-5v7j-vr7h","ROOT-OS-DEBIAN-11-CVE-2025-38161","ROOT-OS-DEBIAN-12-CVE-2025-38161","ROOT-OS-UBUNTU-2204-CVE-2025-38161","ROOT-OS-UBUNTU-2404-CVE-2025-38161","UBUNTU-CVE-2025-38161"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel RDMA driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel RDMA mlx5 driver allows attackers to cause a denial of service or potentially execute code via improper error handling during RQ destruction.","user_interaction":"not_required","vuln_class":"use_after_free"},"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":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mlx5: Fix error flow upon firmware failure for RQ destruction\n\nUpon RQ destruction if the firmware command fails which is the\nlast resource to be destroyed some SW resources were already cleaned\nregardless of the failure.\n\nNow properly rollback the object to its original state upon such failure.\n\nIn order to avoid a use-after free in case someone tries to destroy the\nobject again, which results in the following kernel trace:\nrefcount_t: underflow;
