from what they demonstrated, this seems to only be a $100,000 exploit in Apple's bug bounty platform, but if they package it right, it could be a $1.5 million exploit

They simply have to show it against a beta version of MacOS, and frame it as unauthorized access, and maybe from locked mode if possible

unfortunately a little light on the details. I'm very curious how the bug survived through MTE

GPU memory/shaders/etc. isn't protected by MTE or PAC. They said "data-only", so I guess GPU commands could fit into this description.

IIRC, the GPU is behind a memory controller, so I doubt corrupting GPU memory alone could lead to an LPE. But I suppose it would give you someplace to store stuff if you can make something else read from it.

This is an lpe I believe what you’re describing is a zero click rce.

how much do you think it is worth in the bug bounty program
