Linux Kernel GPIO Xilinx Integer Overflow Vulnerability Allowing Configuration of More Than 32 Pins

An integer overflow vulnerability has been identified in the Linux kernel's GPIO Xilinx implementation. The current version cannot configure more than 32 pins due to an incorrect data type. This issue has been addressed by type casting to unsigned long to prevent the overflow.

Impact

Exploitation of this vulnerability could lead to incorrect GPIO pin configuration, potentially allowing for unintended behavior in hardware control.
