Could you build this?
No Discovering or writing a weaponized proof-of-concept exploit for an Apple XNU kernel heap overflow vulnerability (CVE) requires elite binary exploitation and kernel security research skills.
What it would actually take: Creating a viable exploit for an HFS+ kernel vulnerability requires deep knowledge of the macOS XNU kernel heap layout (kalloc zones, kmalloc), corrupting B-tree record parsing logic via crafted disk images, defeating kernel ASLR and PAN/PAC protections, and achieving arbitrary kernel execution. This demands top-tier vulnerability research, reverse engineering of proprietary kernel drivers, and advanced low-level C exploitation skills.
