PS3 PS3 Hen doesn't work when connected to internet

[Sam_Asugi]

Hello,

Hen doesn't work on my ps3 when the console is connected to the internet. Everything works fine when I disable the connection.

I have also tested it on other networks and it worked. But for whatever reason, Hen seems to have some problem with the one I would be using.

Is there a way to stop Hen from accessing the internet on startup?

Go to Network settings and turn off the Media server.

Thanks. Hen froze during startup on the first try with this setting but it seems to work now.
What exactly does this setting do?
Does it stop Hen from checking for updates?

This setting generates more network traffic and somehow interferes with HEN exploitation.

I'll look into this a bit when I get some time.

In my fork, I removed all network-based features, but this issue still occurs here, but only on my mom's network.

Have long been aware..

The HEN exploit relies on socket corruption, to work properly it creates 60 something sockets, which must be aligned in kernel memory in a certain way, then it fills the entire kernel memory in order to make a ioctl syscall execution hang when it tries to allocate memory, then another thread may destroy the socket that the hanging ioctl syscall is using, then it frees kernel memory to let the ioctl syscall complete its memory allocation and continue its job, except that the socket the ioctl syscall validated to use before the memory allocation step is now a closed socket ie Use After Free and krop gadget execution.

A background service like the media server may open and close sockets while the exploit is running and impact the kernel memory layout or the amount of available kernel memory on which the exploit relies to work, the slightest change make the exploit fail..
The same thing goes for PSN, background downloads and all other online background services..
