Vulnerability from variot

In CDMA PPP protocol, there is a possible out of bounds write due to a missing bounds check. This could lead to remote escalation of privilege with no additional execution privilege needed. User interaction is not needed for exploitation. Patch ID: MOLY01068234; Issue ID: ALPS08010003. LR11 , LR12A , LR13 A number of MediaTek products, including the following, contain out-of-bounds write vulnerabilities.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state
