Vulnerability CVE-2021-30883 is a critical memory corruption bug in the IOMobileFrameBuffer, and essentially allows applications to run commands on all vulnerable devices with kernel privileges.

According to Apple, this vulnerability may have been actively exploited in attacks, although it did not provide any details of how. It’s a deliberate tactic that makes it much more difficult for others who have never been able to figure out the feat or reverse engineer the patch for their own benefit.
