Wander Lairson Costa fadd504206 UPSTREAM: netfilter: xt_sctp: validate the flag_info count 
commit e99476497687ef9e850748fe6d232264f30bc8f9 upstream.

sctp_mt_check doesn't validate the flag_count field. An attacker can
take advantage of that to trigger a OOB read and leak memory
information.

Add the field validation in the checkentry function.

Bug: 304913898
Fixes: 2e4e6a17af ("[NETFILTER] x_tables: Abstraction layer for {ip,ip6,arp}_tables")
