Descriptions
In the Linux kernel, the following vulnerability has been resolved:
clk: Get runtime PM before walking tree for clk_summary
Similar to the previous commit, we should make sure that all devices are
runtime resumed before printing the clk_summary through debugfs. Failure
to do so would result in a deadlock if the thread is resuming a device
to print clk state and that device is also runtime resuming in another
thread, e.g the screen is turning on and the display driver is starting
up. We remove the calls to clk_pm_runtime_{get,put}() in this path
because they're superfluous now that we know the devices are runtime
resumed. This also squashes a bug where the return value of
clk_pm_runtime_get() wasn't checked, leading to an RPM count underflow
on error paths.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: clk: Obtenga PM en tiempo de ejecución antes de recorrer el árbol para clk_summary De manera similar a el commit anterior, debemos asegurarnos de que todos los dispositivos se reanuden en tiempo de ejecución antes de imprimir clk_summary a través de debugfs. No hacerlo resultaría en un punto muerto si el subproceso está reanudando un dispositivo para imprimir el estado de clk y ese dispositivo también está reanudando el tiempo de ejecución en otro subproceso, por ejemplo, la pantalla se enciende y el controlador de pantalla se está iniciando. Eliminamos las llamadas a clk_pm_runtime_{get,put}() en esta ruta porque son superfluas ahora que sabemos que los dispositivos se han reanudado en tiempo de ejecución. Esto también soluciona un error por el cual el valor de retorno de clk_pm_runtime_get() no se verificaba, lo que provocaba un desbordamiento insuficiente del recuento de RPM en las rutas de error.
