Published

In the Linux kernel, the following vulnerability has been resolved: pinctrl: bcm2835: Don't remove an unregistered GPIO chip If the devm_pinctrl_register() function fails, bcm2835_pinctrl_probe() calls gpiochip_remove() before gpiochip_add_data() has registered the GPIO chip. This means that upon failure the gpio_chip.gpiodev is NULL resulting in a null pointer dereference inside the gpiochip_remove() function. Remove the unnecessary function call to gpiochip_remove(). No GPIO cleanup is required because the GPIO chip has not yet been registered. Without this change there is potential for a kernel panic upon registration failure
