In the Linux kernel, the following vulnerability has been resolved:

RDMA/mlx5: Fix mlx5_ib_get_hw_stats when used for device

Currently, when mlx5_ib_get_hw_stats() is used for device (port_num = 0),
there is a special handling in order to use the correct counters, but,
port_num is being passed down the stack without any change.  Also, some
functions assume that port_num >=1. As a result, the following oops can
occur.
