Is memtest_vulkan safe?

I've been looking at overclocking my VRAM and came across threads of people recommending memtest_vulkan to test the performance and stability.

https://github.com/GpuZelenograd/memtest_vulkan

It seems to have a Linux build too. Has anyone tried it? Is it safe to use, not just from a hardware standpoint (it doesn't just fry the GPU) but also from a malware standpoint? Anyone maybe even check out the source code?

I see the dev also worked on https://github.com/ihaque/memtestCL which seemed popular back over a decade ago.
