Security researcher Saar Amar has already developed a proof of concept exploit.

In the last iOS security update (15.0.2) Apple fixed a vulnerability in IOMobileFrameBuffer/AppleCLCD, which they specified was exploited in the wild (CVE-2021-30883). This attack surface is highly interesting because it’s accessible from the app sandbox (so it’s great for jailbreaks) and many other processes, making it a good candidate for LPEs exploits in chains (WebContent, etc.).
