Neither this thread nor the video in it suggest anything. If I was a mod I would lock it.

I don't see how that's an exploit. It could just be a simple bug/crash. Anyway, try not to post WIP topics.

white and green screen flasher

Code: Select all

    typedef unsigned int u32;

    void ColorVRAM(u32 color)
    {
    int i;

    for(i = 0x44000000; i < 0x44100000; i += 4)
    {
       (((u32 *)i)[0]) = color;
    }
    }

    void _start() __attribute__ ((section (".text.start")));
    void _start()
    {
       ColorVRAM(0x00FFFFFF); // 0x00FFFFFF is white   
       ColorVRAM(0x0000FF00); // 0x0000FF00 is Pastel Green

Yes it's a POC of the exploit, but many usermode exploits are unable to be ported to vHBL ;)

we try to avoid useless WiP threads, but many people make topics to showcase their exploits in action so I don't see why we should single out this guy for no reason, I mean he did post the code that he's running in the PoC so I doubt he's lying. What I don't agree with is the section, this should be in PSP -> Security, so moving...

Wololo just doesn't like vaporware... As long as you continue to develop it and post meaningful updates, i say go for it!

If the crash has no value to port an exploit to it, then ask the mods to close it I guess?

Look for kernel exploits then, that'd work ;)
