The soundtrigger driver in P9 Plus smart phones with software versions earlier than VIE-AL10BC00B353 has a memory double free vulnerability. An attacker tricks a user into installing a malicious application, and the application can start multiple threads and try to free specific memory, which could triggers double free and causes a system crash or arbitrary code execution.
The product calls free() twice on the same memory address.
