Title		Modem Heap Buffer Overflow Causing Remote Denial of Service

Mon, 04 May 2026 06:45:00 +0000

Type	Values Removed	Values Added
Description		In Modem, there is a possible system crash due to a heap buffer overflow. 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: MOLY01760138; Issue ID: MSV-6148.
Weaknesses		CWE-120
