If your goal is to interrupt her usage to avoid excessive usage, would a pomodoro timer help?
I dunno if that can be setup to force lock the screen or something, but maybe its helpful? Depends if its easy to override?
That’s for the motherboard replacement, not the bootloader unlock.
They’ve already unlocked and bricked their device, so they need a new motherboard.
The claims are well into the “I found a unicorn” territory, I’m tipping its either “If you misconfigure this, its unsafe”, or its a real vuln, and its significantly harder to exploit that they are claiming.
Not all Linux’s have SSH enabled, especially out of the box.
They have some other posts about IPv6 parsing (also not universal), but that doesnt sound like an “easy” RCE.
For free? Probably not.
Wireguard has been audited by some University groups, maybe contact one of them:
Doesn’t even startup on my box, but doesn’t crash the kernel or system either, just regular application crash
Kernel shouldn’t crash, and anything running in memory will be okayish, but it definitely will get less and less stable. It won’t be possible to start new processes.
I have a Linux install on a USB SSD with a flakey connection, if I bumped the cord the root would unmount. It was fairly resilient, but graphics would slowly start disappearing. I’m fairly sure I could cleanly reboot as long as I had a terminal open, but its been a while, so maybe I’m misremembering.
Still, the overall system becomes pretty useless, so i guess its fair to call it a crash
touch

There are rust libraries to send signals, might be better to use those rather than calling bash. eg. https://docs.rs/nix/latest/nix/sys/signal/index.html
I’m guessing if input was “”, then it would sigkill all processes? Less confident, but some functions behave slightly differently in an interactive console vs a non interactive, maybe ps
has a different format when used non interactively?
Aside, you want three backticks and a newline to get code formatting :)
Ah, that definitely would feel like a crash. Sent kill signal to cgroup accidentally? Or just iterate over all processes and signal them all?
OPs example was task management, which doesn’t require kernel modules.
Doesn’t explain OPs task management example. And won’t crash the kernel, just make things unresponsive
That won’t crash your kernel, and I was more curious about the OPs example. Task management is basically reading some files, and sending signals, it should be near impossible to crash the system.
How are you crashing your system?! Crashing program sure, but the entire system?
Yeah, we’ll get into that right after we solve SQL injection vulnerabilities. Don’t rush us.
Sway-wm used to be spawnable as a child window, not sure if that is still possible.
I think you should also be able to get multiple ctrl-alt-fX graphical sessions.
I’ll come back and update this comment when I get to my PC and give this a try.
Edit: seem Max-P’s comment.
