kernel: sctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A race condition exists in the SCTPSENDALL path where a cached list entry is not properly revalidated after the socket lock is temporarily released. This allows a local attacker or a remote attacker v...
