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, if a malicious actor has already obtained the System privilege. User interaction is needed for exploitation. Patch ID: MOLY01923663 / ALPS11315955; Issue ID: MSV-10866.
