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-2025-39768 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-2025-39768/ (Markdown: https://insights.sbomify.com/CVE-2025-39768/index.md)","id":"CVE-2025-39768","markdown":"https://insights.sbomify.com/CVE-2025-39768/index.md","name":"CVE-2025-39768","record":{"aliases":["BELL-CVE-2025-39768","DEBIAN-CVE-2025-39768","GHSA-9vj3-c3f5-qhqx","UBUNTU-CVE-2025-39768"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A flaw in the Linux kernel's mlx5 network driver causes soft lock-ups during complex rule rehash errors, leading to system denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: HWS, fix complex rules rehash error flow\n\nMoving rules from matcher to matcher should not fail.\nHowever, if it does fail due to various reasons, the error flow\nshould allow the kernel to continue functioning (albeit with broken\nsteering rules) instead of going into series of soft lock-ups or\nsome other problematic behaviour.\n\nSimilar to the simple rules, complex rules rehash logic suffers\nfrom the same problems.
