Linux Kernel cpufreq CPPC Vulnerability Overflow Issue

Vulnerability

A vulnerability in the Linux kernel's cpufreq CPPC implementation could lead to integer overflow. The vulnerability arises because the fields of the _CPC object are unsigned 32-bit values. To prevent potential overflows when using these values, 'u64' casts have been added.

Impact

The vulnerability could cause integer overflow, potentially leading to unexpected behavior or exploitation.
