Remote code execution via unchecked UUID concatenation
Published Dec 2, 2024 · Updated Dec 3, 2024
Out-of-bounds write in Android 6 through 8.1 Bluetooth storage allows remote attackers to execute code via a crafted UUID list. In prop2cfg, each UUID was converted to text and appended with strcat to a 1,024-byte stack buffer without checking the accumulated output length. No privileges or user interaction are required, but the target must process attacker-controlled Bluetooth properties; successful exploitation executes code in the Bluetooth service context.
