In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix mlx5_poll_one() cur_qp update flow When cur_qp isn't NULL, in order to avoid fetching the QP from the radix tree again we check if the next cqe QP is identical to the one we already have. The bug however is that we are checking if the QP is identical by checking the QP number inside the CQE against the QP number inside the mlx5_ib_qp, but that's wrong since the QP number from the CQE is from FW so it should be matched against mlx5_core_qp which is our FW QP number. Otherwise we could use the wrong QP when handling a CQE which could cause the kernel trace below. This issue is mainly noticeable over QPs 0 & 1, since for now they are the only QPs in our driver whereas the QP number inside mlx5_ib_qp doesn't match the QP number inside mlx5_core_qp.
