Description
A flaw was found in the Linux kernel's Zynq General Purpose Input/Output (GPIO) driver. A local user could cause a Denial of Service (DoS) when requesting a GPIO line fails due to improper reference count handling in the runtime power management subsystem. The error path fails to decrement the usage counter, preventing the controller from entering a low-power suspend state. Consequently, system clocks remain permanently enabled, leading to resource leaks and continuous power consumption.
