Analyst Note
This CVE is confirmed as actively exploited in the wild with kernel-level privilege escalation capability (CVSS 7.8 HIGH). Google Project Zero attribution, multiple coordinated Apple security patches across iOS/macOS/watchOS platforms, and media reports of 'extremely sophisticated' attacks provide strong corroboration of active exploitation.
