I’m skeptical of sharing incomplete work publicly we’ve seen scams like Elhout and Progg before. As a newbie, remember devs have a responsibility to the community. Only share what you’ve properly confirmed. Otherwise people will etawen and troll you for failure.

@MHasyimy It is a UAF, UAF fires deferred (async GPU completion callback, after the ioctl returns rv=0), not during ioctl execution I've pre-injected CE_KPTR + ibuf2=oracle_dmap into fd=42's gc_proc_ctx before close, and the freed heap retained the data

@explicitth1nker The panic during 0xC0048116 might be UAF. The 'metadata vs callback' issue is likely a heap alignment problem. Since fd=42 uses fences, you should spray the heap after the close? but before the ioctl finishes to overlap the fence with a fake callback struct. Should u try the NOP?

just randomly thought about this i remember a bug where backing up your ps4 and restoring it would remove the need to insert the disc every time you wanted to boot up the game thats how i first played gta v, my friend let me borrow his disc and once i restored i gave it back

I will analyze the ps4 13.50 kernel's elf dump later.... for now I only analyze the ps4 11.00 one (cus only most easiest obtainable kernel dump from my own jailbroken ps4) and found the no mtx_lock function on the /dev/gc driver function.

C() Meta /dev/gc character device (GPU command processor) has a missing mtx lock Thread A: ioctl(fd_fc, CMD, ibuf_of_kptrs) writes user controlled data to gc_proc_ctx Thread B: open("/dev/gc"), gc_proc/ctx freed while Thread A writes BC emu reads kptr as function pointer
