Trust: 0.6

sources: CNVD: CNVD-2022-66248

DESCRIPTION

In CCCI, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06641673; Issue ID: ALPS06641653. MediaTek Inc. is the world's fourth largest fab semiconductor company, with a leading position in mobile terminals, smart home applications, wireless connectivity technologies and IoT products, with approximately 1.5 billion units a year End products with built-in MediaTek chips are available worldwide.
