Description
A flaw was found in the Linux kernel's Intel Speed Select Technology (ISST) power management component for x86 platforms. When a system resumes from suspend, the SST-PP control settings for all power domains are not fully restored, affecting only power domain 0. This occurs due to an incorrect base address being used during the restore process, which could lead to unexpected system behavior or suboptimal power management for other power domains.
