It has been classified as critical. This affects some unknown processing of the component Base Station Handler. The manipulation with an unknown input leads to a uncaught exception vulnerability. CWE is classifying the issue as CWE-248. An exception is thrown from a function, but it is not caught. This is going to have an impact on availability. The summary by CVE is:

In Modem, there is a possible system crash due to an incorrect bounds 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: MOLY01689251; Issue ID: MSV-4840.

The advisory is shared at corp.mediatek.com. This vulnerability is uniquely identified as CVE-2025-20754 since 11/01/2024. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

Applying the patch MSV-4840 is able to eliminate this problem.

The vulnerability is also documented in the vulnerability database at CERT Bund (WID-SEC-2025-2711). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
