{"id":"CVE-2026-31416","summary":"netfilter: nfnetlink_log: account for netlink header size","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nfnetlink_log: account for netlink header size\n\nThis is a followup to an old bug fix: NLMSG_DONE needs to account\nfor the netlink header size, not just the attribute size.\n\nThis can result in a WARN splat + drop of the netlink message,\nbut other than this there are no ill effects.","modified":"2026-06-04T09:14:27.388522763Z","published":"2026-04-13T13:21:03.974Z","related":["SUSE-SU-2026:2068-1","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/2026/31xxx/CVE-2026-31416.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/09883bf257f4243ed5a1fd35078ec6f0d0f3696a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4ec216410fac9de83c99177a160ebb8d42fad075"},{"type":"WEB","url":"https://git.kernel.org/stable/c/607245c4dbb86d9a10dd8388da0fb82170a99b61"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6b419700e459fbf707ca1543b7c1b57a60fedb73"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6d52a4a0520a6696bdde51caa11f2d6821cd0c01"},{"type":"WEB","url":"https://git.kernel.org/stable/c/761b45c661af48da6a065868d59ab1e1f64fd9b6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/88a8f56e6276f616baad4274c6b8e4683e26e520"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f08ffa3e1c8e36b6131f69c5eb23700c28cbd262"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31416.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31416"},{"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":"9dfa1dfe4d5e5e66a991321ab08afe69759d797a"},{"fixed":"4ec216410fac9de83c99177a160ebb8d42fad075"},{"fixed":"09883bf257f4243ed5a1fd35078ec6f0d0f3696a"},{"fixed":"761b45c661af48da6a065868d59ab1e1f64fd9b6"},{"fixed":"607245c4dbb86d9a10dd8388da0fb82170a99b61"},{"fixed":"6b419700e459fbf707ca1543b7c1b57a60fedb73"},{"fixed":"88a8f56e6276f616baad4274c6b8e4683e26e520"},{"fixed":"f08ffa3e1c8e36b6131f69c5eb23700c28cbd262"},{"fixed":"6d52a4a0520a6696bdde51caa11f2d6821cd0c01"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"3a758a2b78da2f49f7165678faf999e946a0c4b5"},{"last_affected":"131172845aa2c804ffa9423455aee585061ea35e"},{"last_affected":"b1fef6b81871a396f3b8702077333e769673c87b"},{"last_affected":"add9183d993c12fb61ce0a674a424341d5be5b36"}]}],"versions":["v3.17.3","v3.14.24","v3.10.60","v3.12.33","v3.17","v3.17.2","v3.14.23","v3.10.59","v3.12.32","v3.17.1","v3.14.22","v3.10.58","v3.17-rc1","v3.12.31","v3.14.21","v3.10.57","v3.17-rc7","v3.14.20","v3.10.56","v3.17-rc2","v3.10.55","v3.14.19","v3.17-rc4","v3.16","v3.17-rc5","v3.17-rc6","v3.12.30","v3.12.29","v3.14.18","v3.10.54","v3.17-rc3","v3.12.28","v3.14.17","v3.10.53","v3.12.27","v3.16-rc7","v3.14.16","v3.10.52","v3.14.15","v3.10.51","v3.16-rc1","v3.16-rc3","v3.10.50","v3.14.14","v3.12.26","v3.16-rc5","v3.16-rc6","v3.14.13","v3.10.49","v3.16-rc2","v3.16-rc4","v3.12.25","v3.14.12","v3.10.48","v3.12.24","v3.13","v3.14.11","v3.10.47","v3.15","v3.14.10","v3.10.46","v3.14.9","v3.10.45","v3.14.8","v3.10.44","v3.12.23","v3.12.22","v3.10.43","v3.14.7","v3.10.42","v3.14.6","v3.15-rc5","v3.10.41","v3.14.5","v3.15-rc8","v3.15-rc1","v3.15-rc6","v3.12.21","v3.15-rc3","v3.14.4","v3.10.40","v3.15-rc7","v3.15-rc2","v3.15-rc4","v3.14","v3.12.20","v3.10.39","v3.14.3","v3.14.2","v3.10.38","v3.12.19","v3.14-rc4","v3.14.1","v3.10.37","v3.12.18","v3.14-rc8","v3.10.36","v3.12.17","v3.14-rc7","v3.14-rc6","v3.14-rc1","v3.14-rc2","v3.10.35","v3.12.16","v3.10.34","v3.14-rc5","v3.12.15","v3.10.33","v3.14-rc3","v3.12.14","v3.10.32","v3.12.13","v3.12.12","v3.10.31","v3.12.11","v3.10.30","v3.12.10","v3.10.29","v3.13-rc6","v3.12.9","v3.10.28","v3.12.8","v3.10.27","v3.13-rc8","v3.12","v3.13-rc7","v3.13-rc1","v3.12.7","v3.10.26","v3.13-rc4","v3.13-rc3","v3.12.6","v3.10.25","v3.13-rc5","v3.13-rc2","v3.12.5","v3.10.24","v3.12.4","v3.10.23","v3.10.22","v3.12.3","v3.12.2","v3.10.21","v3.12.1","v3.10.20","v3.10.19","v3.12-rc7","v3.12-rc3","v3.12-rc6","v3.10.18","v3.12-rc1","v3.12-rc5","v3.11","v3.10.17","v3.12-rc2","v3.12-rc4","v3.10.16","v3.10.15","v3.10.14","v3.10.13","v3.10.12","v3.10.11","v3.11-rc7","v3.10.10","v3.11-rc2","v3.11-rc5","v3.11-rc1","v3.11-rc3","v3.11-rc4","v3.10.9","v3.11-rc6","v3.10.8","v3.10.7","v3.10.6","v3.10.5","v3.10-rc2","v3.10.4","v3.10.3","v3.10.2","v3.10","v3.10.1","v3.10-rc7","v3.10-rc6","v3.10-rc1","v3.10-rc5","v3.10-rc3","v3.10-rc4","v3.9","v3.9-rc2","v3.9-rc7","v3.9-rc8","v3.9-rc3","v3.9-rc6","v3.9-rc5","v3.9-rc4","v3.9-rc1","v3.8","v3.8-rc7","v3.8-rc6","v3.8-rc5","v3.8-rc2","v3.8-rc1","v3.8-rc3","v3.8-rc4","v3.7","v3.7-rc1","v3.6","v3.7-rc6","v3.7-rc7","v3.7-rc3","v3.7-rc8","v3.7-rc2","v3.7-rc4","v3.7-rc5","v3.6-rc7","v3.6-rc1","v3.5-rc3","v3.6-rc6","v3.6-rc5","v3.5","v3.6-rc3","v3.6-rc4","v3.6-rc2","v3
