In the Linux kernel, the following vulnerability has been resolved: platform/x86: x86-android-tablets: hold device reference for secondary fwnode teardown In gpio_secondary_fwnode_init(), acpi_bus_find_device_by_name() returns a device reference, but the local dev variable is declared with __free(put_device), dropping the reference at the end of each iteration. Meanwhile, devm_add_action_or_reset() saves the dev pointer for gpio_secondary_unset() without incrementing its reference count, which could lead to a use-after-free during driver teardown if the device is released in the interim. Acquire an explicit device reference with get_device() when registering the devres action, and drop it with put_device() inside gpio_secondary_unset().

A flaw was found in the Linux kernel's x86-android-tablets driver. During device initialization, the driver saves a pointer to a device structure without incrementing its reference count, while dropping the active reference prematurely. If the device is released before driver teardown, a local user could trigger a use-after-free condition. This flaw can lead to a Denial of Service (DoS) through a system crash or potentially allow privilege escalation.
