In Modem, there is a possible out of bounds read due to a missing permission 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: MOLY01774038; Issue ID: MSV-8914.

In Modem, there is a possible out of bounds read due to a missing permission 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: MOLY01774038; Issue ID: MSV-8914.
