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.

Mientras que el cambio de velocidad de reloj de CPUX de PLL cuando la CPU se est\u00e1 ejecutando, funciona en la gran mayor\u00eda de los casos, de vez en cuando provoca inestabilidad. Esto provoca fallos del sistema y otros comportamientos indefinidos. Despu\u00e9s de muchas pruebas (m\u00e1s de 30 horas) y al mismo tiempo realizar muchos cambios de frecuencia, ya no podemos observar ning\u00fan problema de inestabilidad al realizar la reparaci\u00f3n a un reloj estable como un oscilador de 24 MHz."
