Summary
In the Linux kernel, the following vulnerability has been resolved: clk: sunxi-ng: h6: Reparent CPUX during PLL CPUX rate change While PLL CPUX clock rate change when CPU is running from it works in vast majority of cases, now and then it causes instability. This leads to system crashes and other undefined behaviour. After a lot of testing (30+ hours) while also doing a lot of frequency switches, we can't observe any instability issues anymore when doing reparenting to stable clock like 24 MHz oscillator.
