AI-suggested
A fix is available that changes the registration function to devm_gpiochip_add_data(), ensuring proper device-managed lifecycle handling. Users should update to the fixed Linux kernel version containing this patch once it is released. No additional mitigation is indicated.
Description
A use-after-free vulnerability in the Linux kernel's MediaTek pinctrl driver was fixed by changing the GPIO chip registration to use device-managed memory functions. The issue occurred because the gpio_chip was allocated with device-managed memory but registered without it, causing potential use-after-free when the driver is built as a module and unloaded.
