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-2023-54035 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-2023-54035/ (Markdown: https://insights.sbomify.com/CVE-2023-54035/index.md)","id":"CVE-2023-54035","markdown":"https://insights.sbomify.com/CVE-2023-54035/index.md","name":"CVE-2023-54035","record":{"aliases":["BELL-CVE-2023-54035","DEBIAN-CVE-2023-54035","GHSA-pcf2-g46w-wp92","ROOT-OS-DEBIAN-11-CVE-2023-54035","ROOT-OS-UBUNTU-2204-CVE-2023-54035","UBUNTU-CVE-2023-54035"],"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 double decrement of the chain reference counter in Linux kernel netfilter can cause an underflow, potentially leading to a denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_tables: fix underflow in chain reference counter\n\nSet element addition error path decrements reference counter on chains\ntwice: once on element release and again via nft_data_release().\n\nThen, d6b478666ffa (\"netfilter: nf_tables: fix underflow in object\nreference counter\") incorrectly fixed this by removing the stateful\nobject reference count decrement.\n\nRestore the stateful object decrement as in b91d90368837 (\"netfilter:\nnf_tables: fix leaking object reference count\") and let\nnft_data_release() decrement the chain reference counter, so this is\ndone only once.","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":"netfilter: nf_tables: fix underflow in chain reference counter","id":"CVE-2023-54035","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"wifi: rtl8xxxu: Fix memory leaks with RTL8723BU, RTL8192EU","id":"CVE-2023-54036"},"packages":[],"prev":{"headline":"iommufd: Make sure to zero vfio_iommu_type1_info before copying to user","id":"CVE-2023-54034"},"products":["Linux"],"published":"2025-12-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A double decrement of the chain reference counter in Linux kernel netfilter can cause an underflow, potentially leading to a denial of service.","url":"https://insights.sbomify.com/CVE-2023-54035/"}
