Descriptions
In the Linux kernel, the following vulnerability has been resolved:
gpio: mockup: fix NULL pointer dereference when removing debugfs
We now remove the device's debugfs entries when unbinding the driver.
This now causes a NULL-pointer dereference on module exit because the
platform devices are unregistered *after* the global debugfs directory
has been recursively removed. Fix it by unregistering the devices first.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: gpio: maqueta: corrige la desreferencia del puntero NULL al eliminar debugfs Ahora eliminamos las entradas debugfs del dispositivo al desvincular el controlador. Esto ahora provoca una desreferencia del puntero NULL al salir del módulo porque los dispositivos de la plataforma no están registrados *después* de que el directorio global debugfs se haya eliminado de forma recursiva. Solucionarlo cancelando el registro de los dispositivos primero.
