Descriptions

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

gpiolib: cdev: fix uninitialised kfifo

If a line is requested with debounce, and that results in debouncing
in software, and the line is subsequently reconfigured to enable edge
detection then the allocation of the kfifo to contain edge events is
overlooked. This results in events being written to and read from an
uninitialised kfifo. Read events are returned to userspace.

Initialise the kfifo in the case where the software debounce is
already active.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: gpiolib: cdev: corrige kfifo no inicializado Si se solicita una línea con antirrebote, y eso resulta en un antirrebote en el software, y la línea se reconfigura posteriormente para habilitar la detección de bordes, entonces se realiza la asignación del Se pasa por alto kfifo para contener eventos de borde. Esto da como resultado que los eventos se escriban y lean desde un kfifo no inicializado. Los eventos leídos se devuelven al espacio de usuario. Inicialice el kfifo en el caso de que el software antirrebote ya esté activo.
