| [[Bluetooth_Driver_services|bluetooth]] gatt_process_notification stack buffer overflow
| gatt_process_notification is the GATT handler for processing notification/indication messages. gatt_process_notification does memcpy to stack from the input bt msg data, without size validation. The input len param isn't validated in this func either - if the remaining len following op_code is less than 2, a negative value will be used for the data copy to stack.
These were fixed by adding a bounds check for the size, size==0 is also checked for now.

Note that partial overwrite isn't an option: this is the func that initializes those fields to begin with, it just does deinit first before initializing hashcx/hashobj (prior to that these fields would be all-zero when not overwritten by the buf-overflow).
