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-2023-52742 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-2023-52742/ (Markdown: https://insights.sbomify.com/CVE-2023-52742/index.md)","id":"CVE-2023-52742","markdown":"https://insights.sbomify.com/CVE-2023-52742/index.md","name":"CVE-2023-52742","record":{"aliases":["BELL-CVE-2023-52742","DEBIAN-CVE-2023-52742","GHSA-j77x-x992-6j7f","UBUNTU-CVE-2023-52742"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"low_privilege","summary":"A logic error in the Linux kernel's plusb USB network driver causes a kernel warning and potential denial of service when handling specific control transfers.","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-670","name":"Always-Incorrect Control Flow Implementation"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: USB: Fix wrong-direction WARNING in plusb.c\n\nThe syzbot fuzzer detected a bug in the plusb network driver: A\nzero-length control-OUT transfer was treated as a read instead of a\nwrite.
