  "description": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/mlx4: Prevent shift wrapping in set_user_sq_size()  The ucmd-\u003Elog_sq_bb_count variable is controlled by the user so this shift can wrap.  Fix it by using check_shl_overflow() in the same way that it was done in commit 515f60004ed9 (\u0022RDMA/hns: Prevent undefined behavior in hns_roce_set_user_sq_size()\u0022).",
