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