## Overview

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

platform/x86: ISST: Restore SST-PP control to all domains

The SST-PP control offset is only restored to power domain 0 after
resume. During suspend, control values are read and stored for all
power domains.

Use pd_info->sst_base instead of power_domain_info->sst_base, which
only points to power domain 0 base address.

## Affected

- `Linux >= e3704ce5d7156ee837461be99841f312c64700b0 < cea03d67db3a880893360bdbb1b0b8d9b33b1799`

- `Linux >= dc7901b5a1563a9c9eb29b3b0b0dac3162065cd8 < 2565a28cdcdcb035e151d285efcba26bccb3726e`
- `Linux 2624f3bf45a830cb3b8c8b967b23a72139700562`
- `Linux >= 6.18.16 < 6.18.40`
- `Linux >= 6.19.6 < 6.20`
