Security researchers at Paradigm Shift have crafted a new exploit named usbliter8 targeting the SecureROM of Apple’s A12 and A13 chips. This exploit permits arbitrary code execution within SecureROM due to a bug in the Synopsys DWC2 USB controller’s implementation, which creates a buffer underflow when handling USB Setup packets. For successful exploitation, an attacker must physically possess a device with the necessary chip—one running in the deprecated bypass mode for the USB DART inside SecureROM. – The generated text has been blocked by our content filters.
