Method we used (>5 years ago, now) on ps5 to fiddle with mp4 and hv memory: github.com/fail0verflow/pros…
hope it helps for linux!

btw: we first used the included iommu script to bypass iommu and dump x86 kernel text via custom pcie device in m.2 slot - worked first try :')

New blog post about hacking PS VR! We managed to find some major flaws - breaking secure boot and extracting all key material: fail0verflow.com/blog/2022/p…

Translation: We got all (symmetric) ps5 root keys. They can all be obtained from software - including per-console root key, if you look hard enough!

Took a peek at latest PS4 Pro (CUH-72xx, board NVG-001): same southbridge (CXD90046GG), newly marked syscon (A06-C0L2 but still RL78/G13) - so nothing changes in terms of "Aux Hax" stuff :)

Another "PS4 Aux Hax" blog! Using HDMI-CEC to get code exec on all PS4 southbridge versions (including PS4 Pro, etc.), without requiring other parts of the system to be pwned:

Small update to Aux Hax:
Nearly same methods are working against devices on recent PS4 Pro board NVB-003:
Syscon A05-C0L2 (R5F101LL)
Belize southbridge (CXD90046GG)
Belize has ROM readout protection and clears stack...they're learning ;)

The Tegra X1 flaw that both ShofEL2 and Fusée Gelée exploit now has a name: CVE-2018-6242. nvidia.com/en-us/product-sec… cve.mitre.org/cgi-bin/cvenam…

Fun fact: we started upstreaming some patches months ago (working with the linux-tegra community on Tegra X1 support in mainline Linux), so if you've seen anyone else running Linux on the Switch recently... chances are they were running some of our code unknowingly ;-)

Reminder: ShofEL2 cannot be patched in existing units (it will work on *any* firmware, past or future), it allows full access (all keys and secrets), and it is completely undetectable by normal software. You can dual boot Linux and Switch OS with impunity.
In case it wasn't obvious, our Switch coldboot exploit:
* Is a bootrom bug
* Can't be patched (in currently released Switches)
* Doesn't require a modchip to pull off

In utterly, completely unrelated news, here's a sneak peak at a totally brand new Zelda game coming soon to Nintendo Switch.

Protip for @arstechnica: this is Dolphin on Linux, not some dodgy China-only port for the Shield.
