Description

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

The vulnerability exists due to integer overflow in WLAN Firmware when handling beacon template update command from HLOS. A local user can run a specially crafted program to trigger heap overflow and execute arbitrary code with elevated privileges.

Mitigation
Install updates from vendor's website.
