In some rare cases, the file
/proc/[PID]/cmdline
might be empty. This causes nvtop display wrong information about command being executed or even leak some data inside current memory.For example, it might leak something similar to
/etc/passwd
.I'm not sure how htop or ps handle this kind of case, but I think it's OK to display nothing in command section as it's actually empty there.
