## Overview

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

drm/amdgpu: Fix size validation for non-exclusive domains (v4)

Fix amdgpu_bo_validate_size() to check whether the TTM domain manager for the
requested memory exists, else we get a kernel oops when dereferencing "man".

v2: Make the patch standalone, i.e. not dependent on local patches.
v3: Preserve old behaviour and just check that the manager pointer is not
    NULL.
v4: Complain if GTT domain requested and it is uninitialized--most likely a
    bug.

## Affected

- `linux_kernel >= 4.2, < 6.0.19`
- `linux_kernel >= 6.1, < 6.1.5`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.1.5`
