libzephyr.so is vulnerable to Improper Provisioning. The vulnerability arises from an insecure implementation of the provisionee in the prov_pub_key
function of prov_device.c
within the Bluetooth component. If the provisionee has a public key sent out-of-band (OOB), it can be sent back during provisioning and will be accepted.
