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-2023-52925 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-2023-52925/ (Markdown: https://insights.sbomify.com/CVE-2023-52925/index.md)","id":"CVE-2023-52925","markdown":"https://insights.sbomify.com/CVE-2023-52925/index.md","name":"CVE-2023-52925","record":{"aliases":["DEBIAN-CVE-2023-52925","GHSA-cgvr-gqfv-x5mj","UBUNTU-CVE-2023-52925"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel netfilter","requires_auth":"none","summary":"A logic error in Linux kernel nftables causes insertion failures for expired duplicate entries, potentially leading to denial of service.","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":6.2,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/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\nnetfilter: nf_tables: don't fail inserts if duplicate has expired\n\nnftables selftests fail:\nrun-tests.sh testcases/sets/0044interval_overlap_0\nExpected: 0-2 . 0-3, got:\nW: [FAILED]     ./testcases/sets/0044interval_overlap_0: got 1\n\nInsertion must ignore duplicate but expired entries.\n\nMoreover, there is a strange asymmetry in nft_pipapo_activate:\n\nIt refetches the current element, whereas the other -\u003eactivate callbacks\n(bitmap, hash, rhash, rbtree) use elem-\u003epriv.\nSame for .remove: other set implementations take elem-\u003epriv,\nnft_pipapo_remove fetches elem-\u003epriv, then does a relookup,\nremove this.\n\nI suspect this was the reason for the change that prompted the\nremoval of the expired check in pipapo_get() in the first place,\nbut skipping exired elements there makes no sense to me, this helper\nis used for normal get requests, insertions (duplicate check)\nand deactivate callback.\n\nIn first two cases expired elements must be skipped.\n\nFor -\u003edeactivate(), this gets called for DELSETELEM, so it\nseems to me that expired elements should be skipped as well, i.e.\ndelete request should fail with -ENOENT error.","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: don't fail inserts if duplicate has expired","id":"CVE-2023-52925","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"io_uring/rw: split io_read() into a helper","id":"CVE-2023-52926"},"packages":[],"prev":{"headline":"netfilter: nf_tables: don't skip expired elements during walk","id":"CVE-2023-52924"},"products":["Linux"],"published":"2025-02-05","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-23","vendors":["Linux"]},"summary":"A logic error in Linux kernel nftables causes insertion failures for expired duplicate entries, potentially leading to denial of service.","url":"https://insights.sbomify.com/CVE-2023-52925/"}
