In the Linux kernel, the following vulnerability has been resolved:
gpio: graniterapids: Fix vGPIO driver crash
Move setting irqchip.name from probe() function to the initialization of "irqchip" struct in order to fix vGPIO driver crash during bootup.
Crash was caused by unauthorized modification of irqchip.name field where irqchip struct was initialized as const.
This behavior is a consequence of suboptimal implementation of gpioirqchipsetchip(), which should be changed to avoid casting away const qualifier.
