Just to provide a bit more context and hopefully clear some doubts:
- The déjà-vu exploit chain goes browserhax > nvhax > gmmuhax > nspwn > [undisclosed] > warmboothax;
- What is going to be released is a browser exploit for firmware versions 4.0.0 to 6.0.1 and the "nvhax" exploit which allows you to take over the nvservices' process and access the GPU MMU (which we used for gmmuhax).
I know it's not much yet, but this will grant those with ipatched units the ability to explore the system further and look for even more vulnerabilities on a higher privilege level.
For general users (with ipatched units), the benefits will depend on the firmware version you are on:
- 4.1.0: vulnerable to the entire déjà-vu chain so it can go up to nspwn right away (full userland takeover and therefore, homebrew);
- 5.0.0 to 5.1.0: nspwn was patched in this version, but workarounds are possible by abusing gmmuhax;
- 6.0.0 to 6.0.1: many changes made exploitation really hard to achieve, but there are still workarounds.
6.1.0 patched the browser exploit that will be released (others are already being worked on) and 6.2.0 patched "nvhax" (closing down the current exploit chain).
