Apple Multiple Products Type Confusion Vulnerability
What it is
A type confusion issue affecting multiple Apple products allows processing of maliciously crafted web content, leading to arbitrary code execution.
Who's affected
Affects anyone running Macs, iPhones, or iPads in the office. For a small practice, Apple endpoints are typically how staff handle email, browse client portals, and store local case files — exploitation gives an attacker access to that data on the device.
What to do
Apply updates per vendor instructions.
CISA action deadline: May 25, 2022. Federal agencies must complete the required action by this date. For private SMBs the deadline is advisory — but treat it as a strong recommendation, especially if you handle regulated data (HIPAA, GLBA, ABA model rules).
If you don't have someone in-house to verify the patch deployed across every endpoint — or you're not sure whether you're affected — that's exactly the kind of triage we do. Book a free 20-minute triage call.
