In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, voice_svc_dev is allocated as a device-managed resource. If error cdev_alloc_err occurs, device_destroy will free all associated resources, including voice_svc_dev leading to a double free.

Weakness

The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
