Physical privilege escalation via unchecked DA write
Published Apr 7, 2025 · Updated Apr 7, 2025
Out-of-bounds write in MediaTek DA on affected chipsets allows physically proximate attackers to escalate privileges without authentication. The DA component omits a bounds check before writing, allowing crafted physical-device input to corrupt memory beyond the intended boundary. Physical access is required, but no prior execution privileges or user interaction are needed; successful exploitation grants elevated device privileges.
