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-2024-42073 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-2024-42073/ (Markdown: https://insights.sbomify.com/CVE-2024-42073/index.md)","id":"CVE-2024-42073","markdown":"https://insights.sbomify.com/CVE-2024-42073/index.md","name":"CVE-2024-42073","record":{"aliases":["AZL-47130","AZL-47143","BELL-CVE-2024-42073","DEBIAN-CVE-2024-42073","GHSA-c3g7-jwpr-vrhq","UBUNTU-CVE-2024-42073"],"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 driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel mlxsw driver allows local attackers to cause memory corruption, potentially leading to code execution or system crashes.","user_interaction":"not_required","vuln_class":"use_after_free"},"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-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmlxsw: spectrum_buffers: Fix memory corruptions on Spectrum-4 systems\n\nThe following two shared buffer operations make use of the Shared Buffer\nStatus Register (SBSR):\n\n # devlink sb occupancy snapshot pci/0000:01:00.0\n # devlink sb occupancy clearmax pci/0000:01:00.0\n\nThe register has two masks of 256 bits to denote on which ingress /\negress ports the register should operate on.
