The emerg_data driver in CAM-L21C10B130 and earlier versions, CAM-L21C185B141 and earlier versions has a buffer overflow vulnerability. An attacker with the root privilege of the Android system can tricks a user into installing a malicious application on the smart phone, and send given parameter to smart phone to crash the system or escalate privilege.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
