General notes

• The challenge really uses a stock v5.15.201 kernel with the given .config and the applied kernel.diff
  • The chall_config.diff is just there for your convenience, the 9p stuff is so the host dir can be mounted in QEMU.
  • You can download the bzImage or build it yourself, but you shouldn't really need it.
• The basic_linux_env is just a minimal shell environment to run a linux kernel, you can clone it yourself for testing.
• The flag is accessible in the qemu VM at /flag
