Description

The kernel in Apple iOS before 9.3, OS X before 10.11.4, tvOS before 9.2, and watchOS before 2.2 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app, a different vulnerability than CVE-2016-1754.

In plain language

AI Worth attention

This is a vulnerability in older Apple mobile/desktop operating systems where a specially crafted app could crash the device or potentially run code with high privileges; small businesses should update if they’re still using iOS < 9.3, OS X < 10.11.4, tvOS < 9.2, or watchOS < 2.2.

Executive summary

CVE-2016-1755 is a kernel memory-corruption flaw in Apple iOS/OS X/tvOS/watchOS that can be triggered by a crafted app, potentially leading to privileged code execution or denial of service on vulnerable versions.

What to do now

  1. Check each device’s OS version (iOS, macOS/OS X, tvOS, watchOS) and confirm whether it is older than iOS 9.3, OS X 10.11.4, tvOS 9.2, or watchOS 2.2.
  2. Upgrade any affected devices to the fixed versions: iOS 9.3 or newer, OS X 10.11.4 or newer, tvOS 9.2 or newer, or watchOS 2.2 or newer.
  3. If you cannot update immediately, avoid installing or opening untrusted apps until you upgrade, since the issue is triggered by a crafted app.
