Deathray: a WebGPU shader freezes any M-series Mac from one link, and Apple won't patch it

A researcher published a page that runs an infinite-loop compute shader against a buffer a vertex shader also depends on. That backs up the GPU until WindowServer hangs and the watchdog forces a kernel panic, in Chrome, Firefox and Safari on macOS Tahoe. The bug was disclosed on July 27, and on August 26 Apple said it saw 'no security implications' and reclassified it as an enhancement request. For anyone shipping WebGPU compute to users, it shows how weak GPU isolation is on macOS.
