Please report security issues privately via GitHub Security Advisories rather than a public issue. If that is unavailable, open a minimal issue asking for a private contact and we will follow up.

PenguinBurner performs real GPU hardware operations: enabling persistence mode, setting board power limits, writing core and memory V/F offsets, and taking over fan control. A bad voltage point can hang the GPU, crash the driver, freeze the display, or force a reboot.

Auto-UV records the voltage under test before each risky probe and marks unsafe voltages after a crash, but you run hardware tuning at your own risk. Test changes on hardware you can recover.
