Security readout for executives and security teams
CVE-2016-4655 is an Apple iOS kernel memory disclosure flaw fixed in iOS 9.3.5. A crafted app could expose sensitive memory. Business urgency is higher than the CVSS score suggests because CISA lists it as known exploited and Lookout associated it with the Trident/Pegasus spyware chain. Exposure is concentrated in legacy Apple iOS devices running versions before 9.3.5. Modern managed fleets should have low exposure if minimum OS controls and patch compliance are enforced. Unmanaged, archived, or long-unused devices remain plausible gaps. Prioritize verification for any legacy iOS estate. The vulnerability is old, but KEV status means exploited history is confirmed. The main business risk is unmanaged or unsupported devices used by sensitive personnel. Mitigation focus: Update affected iOS devices to 9.3.5 or later where supported.; Retire or isolate devices that cannot receive the fixed iOS version.; Confirm mobile device management enforces a minimum iOS version..
