So, you have to have had unfettered access to the phone in an unlocked state in order to drop a sufficiently large wall of text into the clipboard prior to the phone being locked? And you're worried about a potential buffer overflow on the locking program itself? How about the malicious actor who already has full access to your phone? Why would he even give a crap about buffer overflows? He can just download and install any number of backdoors...

Emergency calling needs to be enabled, you need to be able to select text from the emergency calling window, and you need access to the camera so you can paste text in the camera.
this exploit also doesn't work with PIN or pattern locks, just password it seems. it also only affects Android 5+. This exploit probably only affects a very small number of devices.
