Physical privilege escalation via unchecked DA write
Published Feb 3, 2025 · Updated Feb 3, 2025
Out-of-bounds write in MediaTek Flash Tool V5 old-arch Lib on Android 12.0, 13.0, 14.0, and 15.0 allows attackers to gain elevated privileges. The DA code writes beyond an allocated buffer because it omits a required bounds check; MediaTek does not identify the affected routine or input format. Exploitation requires physical access and user interaction but no prior execution privileges, and successful exploitation elevates local privileges on an affected device.
