Description

A flaw was found in the Linux kernel's clock (clk) driver for Spacemit's ccu_mix component. An inverted condition within the ccu_mix_trigger_fc() function can cause the system to skip frequency change triggers. This can lead to kernel panics during CPU frequency scaling, resulting in a Denial of Service (DoS) for the system.
