CVE-2026-68417 PUBLISHED

RDMA/siw: publish QP after initialization

Assigner: Linux
Reserved: 30.07.2026 Published: 10.08.2026 Updated: 10.08.2026

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.
