Hacking Scene is quiet, how about a PoC for the Marvell Avastar WiFi SoC?

I've read a few moments ago about a buffer overflow on the firmware for the Marvell Avastar WiFi 88W8897 SoC and a relative PoC that exploit the Valve Steamlink:

In the article it's explained why was used the Steamlink, anyway guess what's inside some PS4 models? (ps4devwiki is down at the moment for me, the Goggle cache works tho)

Let's build undeserved expectations for all the kids with FW higher than 5.07! LOL

I asked on discord when this dropped on twitter and the general consensus was this won’t be useful on PS4 for a long time. Idk why.

Ah, bummer.

To be honest I didn't even completely read that article, only skimmed some parts. When I saw mentioned SoC exploit I thought it was a slam dunk. ^o^;

I would guess WiFi chipset isn't directly used by the primary CPU/APU but instead is available only to the secondary CPU (the one activated by rest mode).
