      "title": "netfilter: nf_log: unregister loggers before per-net teardown",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_log: unregister loggers before per-net teardown\n\nnf_log_syslog and nfnetlink_log unregister their per-network namespace\noperations before unregistering their global logger backends. This\nleaves a window where a sysctl or netlink writer can rebind the still-\nregistered logger after the per-net pre-exit callback cleared the old\nselection.\n\nThe race looks like this:\n\n  CPU 0                                 CPU 1\n  ----                                  ----\n  unregister_pernet_subsys()\n    nf_log_unset(net, logger)\n      net->nf.nf_loggers[pf] = NULL\n\n                                        lock nf_log_mutex\n                                        find logger in loggers[][]\n                                        net->nf.nf_loggers[pf] = logger\n                                        unlock nf_log_mutex\n\n  nf_log_unregister(logger)\n    lock nf_log_mutex\n    loggers[pf][type] = NULL\n    unlock nf_log_mutex\n    synchronize_rcu()\n  module exit returns\n  module core frees backend memory\n\nLater, a sysctl read or packet logging operation can dereference the\nstale per-net logger pointer.\n\nFix this by unregistering the global logger backends before tearing down\nper-net state. Once the global registrations are gone, later writers can\nno longer rebind the logger. unregister_pernet_subsys() already waits\nfor an RCU grace period after the pre-exit callback clears the per-net\nselection, while nf_log_unregister() continues to cover readers of the\nglobal logger table.\n\nApply this ordering fix to both nf_log backends that combine per-net\nteardown with global logger registration.",
