The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect availability. CVE summarizes:

In Modem, there is a possible application crash due to improper input validation. 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: MOLY01707455; Issue ID: MSV-9503.

The advisory is shared for download at mediatek.com. This vulnerability was named CVE-2026-20593 since 11/03/2025. The exploitation appears to be easy. The attack can be initiated remotely.
