+Subject: [PATCH] netfilter: nf_tables: fix potential NULL-ptr deref in
+ nf_tables_dump_obj_done()
+
+If there is no NFTA_OBJ_TABLE and NFTA_OBJ_TYPE, the c.data will be NULL in
+nf_tables_getobj(). So before free filter->table in nf_tables_dump_obj_done(),
+we need to check if filter is NULL first.
+
+Fixes: e46abbcc05aa ("netfilter: nf_tables: Allow table names of up to 255 chars")
