Frequently Asked Questions
1
Which systems are exposed to this issue?
The issue is in the Linux kernel's SpacemiT CCU clock driver and is associated with CPU frequency scaling. Exploitation requires local access with low privileges.
2
What is the practical impact?
The inverted condition can skip the frequency-change trigger during cpufreq scaling, causing kernel panics. The CVSS vector indicates availability impact only, with no stated confidentiality or integrity impact.
3
Is a patch available?
Yes. The vulnerability has been resolved, and patch references are provided for stable kernel trees.
