"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: x86-android-tablets: hold device reference for secondary fwnode teardown\n\nIn gpio_secondary_fwnode_init(), acpi_bus_find_device_by_name() returns a\ndevice reference, but the local dev variable is declared with\n__free(put_device), dropping the reference at the end of each iteration.\nMeanwhile, devm_add_action_or_reset() saves the dev pointer for\ngpio_secondary_unset() without incrementing its reference count, which\ncould lead to a use-after-free during driver teardown if the device is\nreleased in the interim.\n\nAcquire an explicit device reference with get_device() when registering\nthe devres action, and drop it with put_device() inside\ngpio_secondary_unset()."
