Summary
In Modem, there is a possible out of bounds write due to a missing bounds check. This could lead to remote denial of service, 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: MOLY01267281 / MOLY01318201; Issue ID: MSV-6486.
