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-2026-98624 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-2026-98624/ (Markdown: https://insights.sbomify.com/CVE-2026-98624/index.md)","id":"CVE-2026-98624","markdown":"https://insights.sbomify.com/CVE-2026-98624/index.md","name":"CVE-2026-98624","record":{"aliases":["AZL-109172","BELL-CVE-2026-98624","DEBIAN-CVE-2026-98624","GHSA-6phv-j3wg-rfjh","UBUNTU-CVE-2026-98624"],"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":"high_privilege","summary":"A race condition in the Linux kernel netfilter module allows local attackers to cause a system crash via concurrent netlink operations.","user_interaction":"not_required","vuln_class":"race_condition"},"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\nnetfilter: nfnetlink_queue: hold nfnl mutex in event notifier\n\nWe must serialize the release notifier and the config netlink function.\nA concurrent thread can issue close() which can call the release function\nwhile unrelated socket processes UNBIND request for same portid:\n\nOops: general protection fault, [..]\nRIP: 0010:__instance_destroy+0x60/0x210 [nfnetlink_queue]\nCall Trace:\n nfqnl_recv_config+0x9b0/0xdc0 [nfnetlink_queue]\n nfnetlink_rcv_msg+0x7c2/0xeb0\n ? __pfx_nfnetlink_rcv_msg+0x10/0x10\n\nAfter this, parallel UNBIND and URELEASE events are impossible.\n\nThis change isn't nice, but its the shortest fix given instances\nare not refcounted and the nfnetlink config callback drops the\nrcu read lock early due to need for sleeping allocations.","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: nfnetlink_queue: hold nfnl mutex in event notifier","id":"CVE-2026-98624","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"netfilter: flowtable: publish HW_DEAD after worker is done","id":"CVE-2026-98625"},"packages":[],"prev":{"headline":"drm/nouveau/clk: fix list cursor use after loop in nvkm_clk_ustate_update","id":"CVE-2026-98623"},"products":["Linux"],"published":"2026-10-18","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":"2026-10-19","vendors":["Linux"]},"summary":"A race condition in the Linux kernel netfilter module allows local attackers to cause a system crash via concurrent netlink operations.","url":"https://insights.sbomify.com/CVE-2026-98624/"}
