Multiple warning

[anonymousgalaxylord]

Hi,

I am getting issues while doing make fuse or kctf.

make fuse

make kctf

After getting the exploit with warnings, it is not exploiting the kernel.
Could you please help me with that?

Thanks in advance; looking forward to quick fixes.

it's not the warnings; it's probably that the kernel is patched

Basically all non dead distros have patched this.
