Description
A flaw was found in the Linux kernel's Xilinx General Purpose Input/Output (GPIO) driver. When a pin request fails, the driver does not properly decrement the runtime power management reference counter. A local user could trigger this failure to cause a resource leak, preventing the hardware controller from entering a low-power suspend state and keeping device clocks continuously active.
