  "details": "In the Linux kernel, the following vulnerability has been resolved:  netfilter: nfnetlink_log: wait for rcu grace period before freeing pernet state  sashiko reports: \"nfnl_log_net_exit() calls nf_log_unset(), which clears the logger pointer without an RCU grace period.  Immediately after, ops_free_list() frees the per-net state while concurrent packets might still be executing nf_log_packet() under rcu_read_lock().\"  Clear the pointer via .pre_exit to make sure rcu readers have completed before pernet storage is free'd.  The change in nf_log_syslog.c is only done for consistency: it doesn't use pernet data.",
