Description
A flaw was found in the pinctrl: airoha component of the Linux kernel. Without properly handling IRQ (Interrupt Request) resource helpers, the gpiolib (General Purpose Input/Output library) fails to set a flag indicating an IRQ pin is in use. This oversight can allow an unprivileged user or another driver to reconfigure an active IRQ pin, potentially leading to unexpected system behavior or a denial of service.
