Technical details
An information disclosure vulnerability exists in the MediaTek Modem component due to improper input validation. An attacker can exploit this by setting up a rogue base station (eNodeB/gNodeB) and tricking a User Equipment (UE) device into connecting to it. Once connected, the lack of proper validation allows for remote information disclosure from the modem. The vulnerability is tracked by MediaTek under Issue ID MSV-6788 and Patch ID MOLY01811421. No additional execution privileges or user interaction are required for exploitation.
