Personally i dont yet own a PS4, one day im sure i will when i get fully back into gaming, heres news of an exploit that may be too late for most:

qwertyoruiopz reports on Twitter: 'ps4 kernel code exec on 5.00 achieved at last!' Nothing of this posted on so far, but hopefully it will be. Thanks goes to GaryOPA for the heads up. Based on previous tweets from a few days ago, qwerty soldered the same PS4 UART (syscon) interface xorloser released back in August, 2017.
