In WIFI Firmware, there is a possible memory corruption due to a use after free. This could lead to remote escalation of privilege, when devices are connecting to the attacker-controllable Wi-Fi hotspot, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06468872; Issue ID: ALPS06468872.
