Summary
A missing bounds check in the MediaTek modem allows a possible out-of-bounds write (CWE-787) in MediaTek chipsets MT2716, MT2735, MT2737, MT6813, MT6815 and other models. A device that connects to a rogue base station controlled by an attacker could suffer remote privilege escalation, with no additional execution privileges and no user interaction.

Description from the CNA
In Modem, there is a possible out of bounds write due to a missing bounds check. This could lead to remote escalation of privilege, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01778988; Issue ID: MSV-8897.
