Descriptions

In the Linux kernel, the following vulnerability has been resolved:

soc/tegra: regulators: Fix locking up when voltage-spread is out of range

Fix voltage coupler lockup which happens when voltage-spread is out
of range due to a bug in the code. The max-spread requirement shall be
accounted when CPU regulator doesn't have consumers. This problem is
observed on Tegra30 Ouya game console once system-wide DVFS is enabled
in a device-tree.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: soc/tegra: regulators: se corrigió el bloqueo cuando la dispersión de voltaje está fuera de rango. Se corrigió el bloqueo del acoplador de voltaje que ocurre cuando la dispersión de voltaje está fuera de rango debido a un error en el código. . El requisito de dispersión máxima se tendrá en cuenta cuando el regulador de CPU no tenga consumidores. Este problema se observa en la consola de juegos Tegra30 Ouya una vez que se habilita DVFS en todo el sistema en un árbol de dispositivos.
