CVE-2023-54168 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx4: Prevent shift wrapping in set_user_sq_size() The ucmd->log_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 ("RDMA/hns: Prevent undefined behavior in hns_roce_set_user_sq_size()").. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
