In the Linux kernel, the following vulnerability has been resolved:
gpio: exar: initialize the ID before registering its cleanup
devm_add_action_or_reset() invokes the cleanup action immediately when registering the action fails. gpio_exar_probe() currently stores the allocated ID in exar_gpio only after registering the action, so that failure makes exar_devm_ida_free() release ID 0. If the allocated ID is nonzero, this leaks that ID and can free ID 0 belonging to another device.
Store the ID before registering the cleanup action so both the immediate failure path and normal device teardown release the correct allocation.
