Summary
gpio: prevent potential speculation leaks in gpio_device_get_desc()
Details

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

gpio: prevent potential speculation leaks in gpiodeviceget_desc()

Userspace may trigger a speculative read of an address outside the gpio descriptor array. Users can do that by calling gpioioctl() with an offset out of range. Offset is copied from user and then used as an array index to get the gpio descriptor without sanitization in gpiodevicegetdesc().

This change ensures that the offset is sanitized by using arrayindexnospec() to mitigate any possibility of speculative information leaks.

This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.
