kernel: sctp: keep chunk->transport in step with the list it is queued on

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. This use-after-free vulnerability occurs when the system improperly handles chunk transport pointers during the retransmission process. A remote attacker can exploit this by sending specially crafted...
