In Android releases from CAF using the linux kernel (Android for MSM, Firefox OS for MSM, QRD Android) before security patch level 2018-06-05, the function UpdateDeviceStatus() writes a local stack buffer without initialization to flash memory using WriteToPartition() which may potentially leak memory.
The product does not release a resource after its effective lifetime has ended, i.e., after the resource is no longer needed.
