Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> gpiolib: cdev: fix uninitialised kfifo<br /> <br /> If a line is requested with debounce, and that results in debouncing<br /> in software, and the line is subsequently reconfigured to enable edge<br /> detection then the allocation of the kfifo to contain edge events is<br /> overlooked. This results in events being written to and read from an<br /> uninitialised kfifo. Read events are returned to userspace.<br /> <br /> Initialise the kfifo in the case where the software debounce is<br /> already active.
