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-2026-72434 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-2026-72434/ (Markdown: https://insights.sbomify.com/CVE-2026-72434/index.md)","id":"CVE-2026-72434","markdown":"https://insights.sbomify.com/CVE-2026-72434/index.md","name":"CVE-2026-72434","record":{"aliases":["AZL-96341","BELL-CVE-2026-72434","DEBIAN-CVE-2026-72434","GHSA-c7hq-44p5-58fg","UBUNTU-CVE-2026-72434"],"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":"low_privilege","summary":"A race condition in Linux kernel netfilter ipset garbage collection during set destruction can lead to improper shutdown and potential denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"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: ipset: make sure gc is properly stopped\n\nSashiko noticed that when destroying a set,\ncancel_delayed_work_sync() was called while gc\ncalls queue_delayed_work() unconditionally which\ncan lead not to properly shutting down the gc.","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: ipset: make sure gc is properly stopped","id":"CVE-2026-72434","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"netfilter: ipset: fix order of kfree_rcu() and rcu_assign_pointer()","id":"CVE-2026-72435"},"packages":[],"prev":{"headline":"netfilter: nft_meta_bridge: fix NFT_META_BRI_IIFPVID stack leak","id":"CVE-2026-72433"},"products":["Linux"],"published":"2026-08-15","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"A race condition in Linux kernel netfilter ipset garbage collection during set destruction can lead to improper shutdown and potential denial of service.","url":"https://insights.sbomify.com/CVE-2026-72434/"}
