Notice that other registers like 0x1f402016 (CDVD S Command), and 0x1f402004 (CDVD N Command), also are susceptible to buffer overflows, so in total you will find not less than 4 variant vulnerabilities like this, but Considering that the emulator is quasi-unpatchable, and PlayStation's bounty software stopped accepting PS2 emulator escape reports immediately after the 1st 1, there is no explanation to find or analyse other bugs.
0x700000000 (One more weak point in the PS4 ASLR implementation):
