I put my bzImage & kallsyms under kern/ & triggered runFuzz -M M0:
Getting aborted just on attempting dry run:
[*] Spinning up the fork server...
[-] Hmm, looks like the target binary terminated before we could complete a
handshake with the injected code. There are two probable explanations:
- The current memory limit (2.00 GB) is too restrictive, causing an OOM
fault in the dynamic linker. This can be fixed with the -m option. A
simple way to confirm the diagnosis may be:
( ulimit -Sv $[2047 << 10]; /path/to/fuzzed_app )
Tip: you can use http://jwilk.net/software/recidivm to quickly
estimate the required amount of virtual memory for the binary.
- Less likely, there is a horrible bug in the fuzzer. If other options
fail, poke <[email protected]> for troubleshooting tips.

I also tried setting AFL_NO_FORKSRV=1, but didn;t help much:
