Unable to Test the "kvm_vma" | Linux: KVM VM_IO|VM_PFNMAP vma mishandling;-CVE-2021-22543
Since there's no direct context or Readme.md about the repo testing environment;
Based on the limited information on git and the internet findings;
I set my testing environment to;
host machine( ubuntu20 with kernel 5.8.0-41-generic) >> Installed VMM >> created Centos 8.58
The 5.8.041-generic was found from https://github.com/google/security-research/blob/master/pocs/linux/kvm_vma/kernel_code.asm
Why centOS 8.5 is found on https://cve.tuxcare.com/els/cve/CVE-2021-22543
kernel version:
how ever getting error: attempt to define a local label before any non-local labels
Don't understand where am wrong!!! especially about my testing environment
Maybe your nasm version is out of date?
root@1d4f316ade80:/tmp# nasm guest_code.asm -o guest_code
root@1d4f316ade80:/tmp# nasm -v
