Who should care

Apple fleet administrators, endpoint security teams, MDM operators, and users responsible for iOS, macOS, or watchOS devices within the affected version ranges.

Technical summary

The NVD record classifies this issue as CWE-200 with CVSS 3.0 vector CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N. That means the issue is locally reachable, requires user interaction, and primarily impacts confidentiality by allowing disclosure of sensitive kernel memory contents. The supplied record and vendor references point to Apple advisories for the affected products.

Defensive priority

Medium — prioritize patching on any Apple devices still running vulnerable versions, especially managed fleets that may lag in update adoption.

Recommended defensive actions

  • Update affected Apple devices to the vendor-fixed versions referenced by Apple advisories.
  • Inventory iOS, macOS, and watchOS builds to confirm whether any devices remain within the affected ranges.
  • Use MDM or endpoint compliance tooling to verify update deployment and prevent drift back to vulnerable versions.
  • Treat unknown or untrusted app installation pathways as higher risk until systems are fully updated.
  • Review telemetry for unexpected app behavior or abnormal access patterns on unpatched devices.

Evidence notes

This debrief is based on the supplied CVE description, the NVD metadata, and the official Apple advisory links listed in the source record. The CVE was published on 2017-02-20 and modified on 2026-05-13. One data-quality note: the prompt description says affected versions are before iOS 10.2, macOS 10.12.2, and watchOS 3.1.3, while the NVD CPE criteria in the supplied record list end versions of iOS 10.1.1, macOS 10.12.1, and watchOS 2.2.2. Verify exact fixed versions against the Apple advisories.

Official resources

Publicly disclosed in the CVE record on 2017-02-20. The supplied source metadata was later modified on 2026-05-13, but that is not the vulnerability date.
