Who should care

macOS administrators, endpoint security teams, and anyone managing systems that allow local user accounts or untrusted code execution on affected Apple devices.

Technical summary

The NVD record states that macOS versions before 10.12.2 are vulnerable via the IOAcceleratorFamily component. The impact is limited to confidentiality: CVSS 3.0 is AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N, indicating a locally exploitable information disclosure with no integrity or availability impact recorded in the source data.

Defensive priority

Low to moderate. The issue is low severity and requires local access, but kernel memory-layout disclosure can still be relevant for hardening and reducing exposure on managed Macs.

Recommended defensive actions

  • Upgrade affected macOS systems to 10.12.2 or later.
  • Verify fleet inventory for systems running macOS 10.12.1 or earlier and prioritize remediation.
  • Use Apple’s vendor advisory to confirm affected releases and remediation guidance.
  • Treat local-privilege information leaks as a patching priority on shared or high-value endpoints.
