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-2023-53340 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-2023-53340/ (Markdown: https://insights.sbomify.com/CVE-2023-53340/index.md)","id":"CVE-2023-53340","markdown":"https://insights.sbomify.com/CVE-2023-53340/index.md","name":"CVE-2023-53340","record":{"aliases":["BELL-CVE-2023-53340","DEBIAN-CVE-2023-53340","GHSA-cx33-4cq6-86x6","UBUNTU-CVE-2023-53340"],"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":"low_privilege","summary":"A missing check in the Linux kernel mlx5 driver causes an out-of-bounds error when handling unknown DEVX commands, leading to a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"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-129","name":"Improper Validation of Array Index"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: Collect command failures data only for known commands\n\nDEVX can issue a general command, which is not used by mlx5 driver.\nIn case such command is failed, mlx5 is trying to collect the failure\ndata, However, mlx5 doesn't create a storage for this command, since\nmlx5 doesn't use it.
