Stuck when compiled exploit execute

[MarcWarrior]

Hi, Notselwyn

I noticed something you said:

The underlying vulnerability affects all versions (excluding patched stable branches) from v3.15 to v6.8-rc1.

It stuck when trying to execute the compiled exploit, can you advise something? Does it means that my server is not vulnerable?

Thanks.

Hi , Notselwyn
I have run the exploit on my machine with 4.18.0 kernel, it has no result or any output.

I speculate that for your system to be affected by this vulnerability, your Linux kernel version must be one of the versions impacted by it, and the system must have the nf_tables module loaded?

As far as I know, nftables only started being the default firewall in RHEL8, which means that by default, versions of RHEL below 8 do not have the nf_tables module loaded.
