What is CVE-2025-20647?

A vulnerability exists in MediaTek Modem that can lead to a potential system crash due to inadequate bounds checking. This flaw can be exploited remotely when a User Equipment (UE) connects to a malicious base station managed by an attacker. Exploitation does not require any additional execution privileges or user interaction, making this a significant concern for users of the affected MediaTek Modem firmware. It is critical to apply the necessary patches, MOLY00791311 or MOLY01067019, to safeguard against this issue.

Human OS v1.0:
