Inevitable kernel panic after running payloads multiple times

[hippie68]

I have noticed that when loading payloads about 20 times (sometimes slightly more or less), eventually a kernel panic will happen upon closing the WebKit process, which by default is done by read_ptr_at(0), but also happens by other means: by manually closing/reopening the browser, shutting down the PS4, etc.

Perhaps after running the exploits, there may be something left in memory that is not cleaned up properly? I think it is worth investigating further, but that's not something I can do. I thought I should bring this up in case the problem is not known already.
