Description

A flaw was found in the Linux kernel's `pinctrl: single` subsystem. The `pcs_add_gpio_func()` function does not properly release a device node reference after parsing, causing a reference count leak. This continuous leak of resources can lead to system instability and a denial of service (DoS) condition.
