Software vendor:
Qualcomm

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to lack of length check of parameters passed from trusted applications within the Core component. A local application can trigger a buffer overflow and execute arbitrary code with elevated privileges.
