MediaTek chipset: memory corruption
No fix yet
In Modem, there is a possible memory corruption due to a missing bounds check. This could lead to remote escalation of privilege, 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: MOLY01402160; Issue ID: MSV-7298.
