Recommendation: Monitor — no exploitation signal at the moment.

In Modem, there is a possible information disclosure due to improper input validation. This could lead to remote information disclosure, 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: MOLY01811421; Issue ID: MSV-6788.
