In Modem, there is a possible out of bounds write due to an integer overflow. 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: MOLY01872867 / MOLY01774038; Issue ID: MSV-9801.
