An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-52834 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-2023-52834/ (Markdown: https://insights.sbomify.com/CVE-2023-52834/index.md)","id":"CVE-2023-52834","markdown":"https://insights.sbomify.com/CVE-2023-52834/index.md","name":"CVE-2023-52834","record":{"aliases":["BELL-CVE-2023-52834","DEBIAN-CVE-2023-52834","GHSA-9qcj-9374-gfhc","ROOT-OS-DEBIAN-11-CVE-2023-52834","UBUNTU-CVE-2023-52834"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A flaw in the atl1c network driver causes DMA RX overflow errors, potentially leading to denial of service; kernel maintainers should apply the patch.","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":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\natl1c: Work around the DMA RX overflow issue\n\nThis is based on alx driver commit 881d0327db37 (\"net: alx: Work around\nthe DMA RX overflow issue\").\n\nThe alx and atl1c drivers had RX overflow error which was why a custom\nallocator was created to avoid certain addresses.
