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. (NVD)
