Senserva AI Opinion for CVE-2022-22587

Apple's IOMobileFrameBuffer kernel extension carries a memory corruption bug that lets a malicious application execute code with kernel privileges on iOS and macOS, Critical Severity at CVSS 9.8 and confirmed exploited (KEV, 2022-01-28). Kernel-level code execution on a phone means total device compromise, including access to mail, tokens, and MFA apps. The 12% EPSS score is consistent with use in targeted surveillance-style attacks rather than mass campaigns.

Do this: Push the relevant iOS and macOS updates to all Apple devices and audit for devices stuck on old OS builds that can no longer update.
