In the Linux kernel, the following vulnerability has been resolved: pinctrl: mediatek: use devm_gpiochip_add_data() for GPIO chip The gpio_chip is allocated with device-managed memory but registered with the non-managed gpiochip_add_data(). This was harmless while the drivers were built-in, but once they can be built as modules and unbound/rmmod'd, devm frees the gpio_chip's memory while it is still registered, causing a use-after-free. Register it with devm_gpiochip_add_data() so it shares the same device-managed lifecycle, which also lets the manual gpiochip_remove() error paths go away.
