## Overview

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

drm/amdgpu: clean up the amdgpu_cs_parser_bos

In low memory conditions, kmalloc can fail. In such conditions
unlock the mutex for a clean exit.

We do not need to amdgpu_bo_list_put as it's been handled in the
amdgpu_cs_parser_fini.

## Affected

- `Linux >= 737da5363cc07c96d59f2ebaf9f9f87235becf1d < 0905a1d4a5500ecf11f1c0079098e3a351d22163`
- `Linux >= 737da5363cc07c96d59f2ebaf9f9f87235becf1d < f025a2b8d93358467b8e8f4b3a617e88c5f02fab`
- `Linux 6.19`
