CVE-2026-74297 kernel: RDMA/mlx5: Fix undefined shift of user RQ WQE size

CVE-2026-74297 [HIGH] CVE-2026-74297 kernel: RDMA/mlx5: Fix undefined shift of user RQ WQE size
CVE-2026-74297 kernel: RDMA/mlx5: Fix undefined shift of user RQ WQE size
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix undefined shift of user RQ WQE size
set_rq_size() computes the RQ WQE size as "1 << rq_wqe_shift" based on
the user-provided rq_wqe_shift, which is only checked to be greater than
32, so shifts of 32 are still accepted. A shift of 31 also overflows a
signed integer, leading to undefined behavior.
Use check_shl_overflow() to compute the RQ WQE size and reject any
invalid values.
