Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： drm/amd/pm：对 pp_dpm_set_pp_table() 的 memcpy 操作进行边界检查 powerplay 路径中，使用 一次性分配了 。然而，之前的 使用的是通过 sysfs 写入的计数值（最大可达 PAGE_SIZE），且未设置上界限制，从而导致堆溢出。现对写入操作进行限制：当 size 超过 soft_pp_table_size 时，拒绝该写入请求。

Vulnerability Title
drm/amd/pm: bound pp_dpm_set_pp_table() memcpy
Source: CVE Program / CVE List V5
Vulnerability Description
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.
