## Overview

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

RDMA/siw: Remove direct link to net_device

Do not manage a per device direct link to net_device. Rely
on associated ib_devices net_device management, not doubling
the effort locally. A badly managed local link to net_device
was causing a 'KASAN: slab-use-after-free' exception during
siw_query_port() call.

## Affected

- `Linux >= bdcf26bf9b3acb03c8f90387cfc6474fc8ac5521 < 6a97bfc0293db234ac6ec32f6a32bd6702191a95`
- `Linux >= bdcf26bf9b3acb03c8f90387cfc6474fc8ac5521 < 4eafeb4f021c50d13f199239d913b37de3c83135`
- `Linux >= bdcf26bf9b3acb03c8f90387cfc6474fc8ac5521 < 16b87037b48889d21854c8e97aec8a1baf2642b3`
- `Linux 5.3`
