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-2023-52924 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-2023-52924/ (Markdown: https://insights.sbomify.com/CVE-2023-52924/index.md)","id":"CVE-2023-52924","markdown":"https://insights.sbomify.com/CVE-2023-52924/index.md","name":"CVE-2023-52924","record":{"aliases":["BELL-CVE-2023-52924","DEBIAN-CVE-2023-52924","GHSA-4rw8-6238-r9gq","UBUNTU-CVE-2023-52924"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","other"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel netfilter","requires_auth":"low_privilege","summary":"A logic error in Linux kernel netfilter allows memory leaks and kernel warnings when removing expired verdict map elements, potentially leading to denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_tables: don't skip expired elements during walk\n\nThere is an asymmetry between commit/abort and preparation phase if the\nfollowing conditions are met:\n\n1. set is a verdict map (\"1.2.3.4 : jump foo\")\n2. timeouts are enabled\n\nIn this case, following sequence is problematic:\n\n1. element E in set S refers to chain C\n2. userspace requests removal of set S\n3. kernel does a set walk to decrement chain-\u003euse count for all elements\n   from preparation phase\n4. kernel does another set walk to remove elements from the commit phase\n   (or another walk to do a chain-\u003euse increment for all elements from\n    abort phase)\n\nIf E has already expired in 1), it will be ignored during list walk, so its use count\nwon't have been changed.\n\nThen, when set is culled, -\u003edestroy callback will zap the element via\nnf_tables_set_elem_destroy(), but this function is only safe for\nelements that have been deactivated earlier from the preparation phase:\nlack of earlier deactivate removes the element but leaks the chain use\ncount, which results in a WARN splat when the chain gets removed later,\nplus a leak of the nft_chain structure.\n\nUpdate pipapo_get() not to skip expired elements, otherwise flush\ncommand reports bogus ENOENT errors.","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 skip expired elements during walk","id":"CVE-2023-52924","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":7,"next":{"headline":"netfilter: nf_tables: don't fail inserts if duplicate has expired","id":"CVE-2023-52925"},"packages":[],"prev":{"headline":"netfilter: nf_tables: adapt set backend to use GC transaction API","id":"CVE-2023-52923"},"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A logic error in Linux kernel netfilter allows memory leaks and kernel warnings when removing expired verdict map elements, potentially leading to denial of service.","url":"https://insights.sbomify.com/CVE-2023-52924/"}
