If your OS allows writes through stray pointers, you have bigger issues like code exec...<p>Also, ZFS only has it&#x27;s claims to data integrity if you use ECC memory.<p>BTW, anything running on top of the machine is going to be vulnerable to your example, i.e. if you have a program that checksums something, and then writes it to disk, there is opportunity for corruption while it&#x27;s reading the data to checksum it.
