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.
