Description

A flaw was found in the Linux kernel's RDMA/siw component. The siw_create_qp() function prematurely publishes a Queue Pair (QP) before its complete initialization. This allows a Queue Pair Number (QPN) lookup to access a QP that is still under construction, potentially leading to unexpected behavior or system instability.

Statement

This issue affects RDMA siw (Soft-iWARP). QP published to lookup table before initialization completes. Systems not using siw RDMA are not affected.
