Go has no mmap(), import a 3rd party dependency for that and you'll get a segfault the very second you do a mistake.
Python has an mmap module which will catch many memory errors and present them as exception rather than causing a CVE.
I don't agree with the parent comment, but mmap is exposed (low-level) in the standard library and there's a high-level wrapper in x/exp. You need to be careful with mmap no matter where you're using it.
What Go mmap CVE were you thinking of?
