## Overview

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

drm/amd/display: Avoid divide by zero by initializing dummy pitch to 1

[Why]
If the dummy values in `populate_dummy_dml_surface_cfg()` aren't updated
then they can lead to a divide by zero in downstream callers like
CalculateVMAndRowBytes()

[How]
Initialize dummy value to a value to avoid divide by zero.

## Affected

- `linux_kernel >= 6.7, < 6.15.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.15.4`
