## Overview

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

drm/amd/pm: bound pp_dpm_set_pp_table() memcpy

The powerplay path allocates hardcode_pp_table once with kmemdup(...,
soft_pp_table_size). memcpy(..., size) used the sysfs store count (up to
PAGE_SIZE) with no upper bound, causing heap overflow. Reject
writes where size exceeds soft_pp_table_size.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
