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-2023-54030 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2023-54030/ (Markdown: https://insights.sbomify.com/CVE-2023-54030/index.md)","id":"CVE-2023-54030","markdown":"https://insights.sbomify.com/CVE-2023-54030/index.md","name":"CVE-2023-54030","record":{"aliases":["BELL-CVE-2023-54030","DEBIAN-CVE-2023-54030","GHSA-43mh-5pcq-96hp","ROOT-OS-DEBIAN-12-CVE-2023-54030","UBUNTU-CVE-2023-54030"],"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 local attacker can cause a denial of service or out-of-memory condition in the Linux kernel by overflowing multishot recv CQEs in io_uring.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring/net: don't overflow multishot recv\n\nDon't allow overflowing multishot recv CQEs, it might get out of\nhand, hurt performance, and in the worst case scenario OOM the task.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"io_uring/net: don't overflow multishot recv","id":"CVE-2023-54030","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"vdpa: Add queue index attr to vdpa_nl_policy for nlattr length check","id":"CVE-2023-54031"},"packages":[],"prev":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2023-54029"},"products":["Linux"],"published":"2025-12-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A local attacker can cause a denial of service or out-of-memory condition in the Linux kernel by overflowing multishot recv CQEs in io_uring.","url":"https://insights.sbomify.com/CVE-2023-54030/"}
