In short

A flaw in how Apple systems handle very large numbers (integer overflow) could allow a malicious app to run malicious code with the highest system privileges. This is a serious issue because it gives attackers complete control over your device.

Technical detail

An integer overflow vulnerability in Apple's kernel allows a local attacker to bypass input validation and execute arbitrary code with kernel-level privileges. The vulnerability affects multiple iOS, macOS, and watchOS versions; active exploitation has been confirmed in the wild on older iOS versions prior to 15.7.
