## Overview

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

wifi: rtw88: Use devm_kmemdup() in rtw_set_supported_band()

Simplify the code by using device managed memory allocations.

This also fixes a memory leak in rtw_register_hw(). The supported bands
were not freed in the error path.

Copied from commit 145df52a8671 ("wifi: rtw89: Convert
rtw89_core_set_supported_band to use devm_*").

## Affected

- `linux_kernel >= 5.2, < 6.12.75`
- `linux_kernel >= 6.13, < 6.18.16`
- `linux_kernel >= 6.19, < 6.19.6`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.19.6`
