{"id":"CVE-2026-43060","summary":"netfilter: nft_ct: drop pending enqueued packets on removal","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nft_ct: drop pending enqueued packets on removal\n\nPackets sitting in nfqueue might hold a reference to:\n\n- templates that specify the conntrack zone, because a percpu area is\n  used and module removal is possible.\n- conntrack timeout policies and helper, where object removal leave\n  a stale reference.\n\nSince these objects can just go away, drop enqueued packets to avoid\nstale reference to them.\n\nIf there is a need for finer grain removal, this logic can be revisited\nto make selective packet drop upon dependencies.","modified":"2026-06-04T09:14:29.699663909Z","published":"2026-05-05T15:17:26.393Z","related":["SUSE-SU-2026:21841-1","SUSE-SU-2026:21845-1","SUSE-SU-2026:21860-1","SUSE-SU-2026:21876-1","SUSE-SU-2026:21877-1","SUSE-SU-2026:21916-1","SUSE-SU-2026:21919-1","SUSE-SU-2026:2217-1","SUSE-SU-2026:2238-1","openSUSE-SU-2026:20826-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43060.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/36eae0956f659e48d5366d9b083d9417f3263ddc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3da0b946835f33bf36b459ead764c61a761e689b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6802ff8beceb9c4254318e81c1395720438f2cc2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/77da55dee67720e2b8d2db49a53334e6c017ee7b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a64e76933672b08bd85b63086f33432070fd729"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab50302190b303f847c4eba0e31a01a56dec596e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e68a8db3a0546482b34e9ca5ca886bcf73eb37bb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f29a055e4f593e577805b41228b142b58f48df1b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43060.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43060"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"7e0b2b57f01d183e1c84114f1f2287737358d748"},{"fixed":"8a64e76933672b08bd85b63086f33432070fd729"},{"fixed":"3da0b946835f33bf36b459ead764c61a761e689b"},{"fixed":"ab50302190b303f847c4eba0e31a01a56dec596e"},{"fixed":"e68a8db3a0546482b34e9ca5ca886bcf73eb37bb"},{"fixed":"6802ff8beceb9c4254318e81c1395720438f2cc2"},{"fixed":"f29a055e4f593e577805b41228b142b58f48df1b"},{"fixed":"77da55dee67720e2b8d2db49a53334e6c017ee7b"},{"fixed":"36eae0956f659e48d5366d9b083d9417f3263ddc"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43060.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.19.0"},{"fixed":"5.10.253"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.203"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.167"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.130"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.78"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.20"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43060.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
