kernel: RDMA/siw: Reject MPA FPDU length underflow before signed receive math

A flaw was found in the Linux kernel's Soft-iWARP siw component for Remote Direct Memory Access RDMA. A remote attacker can send a specially crafted iWARP Fast Path Data Unit FPDU with a manipulated length field. This manipulation causes an integer underflow, leading to a use-after-free...
