Unisoc VoLTE Video Call Exploit Chain Can Give Attackers Full Android Kernel Access
High
Summary
Security researchers at SSD Secure Disclosure have discovered a two-stage exploit chain that allows attackers to gain full Android kernel access on devices using Unisoc modem firmware. The vulnerability stems from a shared physical memory space between the modem and application processor, and requires an attacker to control a private 4G cellular network and a victim answering an incoming video call. No patches are currently available, and Unisoc has not responded to inquiries about the issue.
