The kernel in Apple iOS before 8.4.1 and OS X before 10.10.5 does not properly restrict the mach_port_space_info interface, which allows attackers to obtain sensitive memory-layout information via a crafted app.

Security readout for executives and security teams

This Apple kernel issue could let a malicious app learn sensitive memory-layout details on iOS before 8.4.1 and OS X before 10.10.5. That information may help attackers build more reliable follow-on attacks, but the sources do not show active exploitation or direct remote compromise. Exposure is most likely on legacy Apple devices still running iOS versions before 8.4.1 or OS X before 10.10.5. Modern, fully updated Apple fleets should not be affected based on the cited fixed-version information. Prioritize this for legacy Apple fleet cleanup, not emergency response. The business risk is highest where old iPhones, iPads, or Macs still run unsupported software and can install apps. Mitigation focus: Update affected iOS devices to 8.4.1 or later where possible.; Update affected OS X systems to 10.10.5 or later where possible.; Retire or isolate Apple devices that cannot receive vendor security updates..
