Recommendation: Monitor — no exploitation signal at the moment.

In Modem, there is a possible system crash due to a logic error. 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: MOLY01106496; Issue ID: MSV-4467.
