Descriptions
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.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: clk: sunxi-ng: h6: CPUX reparent durante el cambio de velocidad de CPUX de PLL. Mientras que el cambio de velocidad de reloj de CPUX de PLL cuando la CPU se está ejecutando, funciona en la gran mayoría de los casos, de vez en cuando provoca inestabilidad. Esto provoca fallos del sistema y otros comportamientos indefinidos. Después de muchas pruebas (más de 30 horas) y al mismo tiempo realizar muchos cambios de frecuencia, ya no podemos observar ningún problema de inestabilidad al realizar la reparación a un reloj estable como un oscilador de 24 MHz.
