- Summary
- netfilter: x_tables: add and use xtables_unregister_table_exit
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
netfilter: xtables: add and use xtablesunregistertableexit
Previous change added xtablesunregistertablepreexit to detach the table from the packetpath and to unlink it from the active table list. In case of rmmod, userspace that is doing set/getsockopt for this table will not be able to re-instantiate the table: 1. The larval table has been removed already 2. existing instantiated table is no longer on the xt pernet table list.
This adds the second stage helper:
unlink the table from the dying list, free the hook ops (if any) and do the audit notification. It replaces xtunregistertable().
