Physical privilege escalation via unchecked DA write
Published Feb 3, 2025 · Updated Feb 3, 2025
Out-of-bounds write in MediaTek Flash Tool V5 Lib adaptor on Android 12.0 through 15.0 allows physically proximate attackers to escalate privileges. The DA component fails to check a buffer boundary before writing attacker-influenced data, permitting a write outside the intended buffer. Exploitation requires physical access and user interaction but no prior execution privileges, and MediaTek has not disclosed the specific buffer or input field.
