Vulnerability Title
RDMA/siw: publish QP after initialization
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siw_create_qp() currently calls siw_qp_add() before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being constructed. Move siw_qp_add() to the end of siw_create_qp(), after QP initialization and before adding the QP to the siw device list.
