Title

RDMA/mlx5: Fix mlx5_ib_get_hw_stats when used for device

Summary

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.

GHSA-2633-6XPW-2GQX

Vulnerability from github – Published: 2025-09-18 15:30 – Updated: 2025-12-12 21:31

Details

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.

Fix it by setting port_num to 1 in order to get device status and remove unused variable.
