Technical details
The vulnerability is a privilege escalation flaw due to improper permissions checking in the modem component. It requires the attacker to already possess System privilege level; from that position, the permissions bypass allows local escalation of privilege (EoP). A patch is available from MediaTek (Patch ID: ALPS09608864 / ALPS09327759).
