Summary

A potential out of bounds write vulnerability exists in MediaTek's KeyInstall software. This issue arises due to a lack of adequate bounds checking, allowing exploitation to occur without user interaction. Successful exploitation could enable a local attacker to escalate their privileges to that of the system. MediaTek has acknowledged this issue and is working on patches to address it.
