A vulnerability was found in Apple Watch OS 1.0 (Smartwatch Operating System). It has been classified as problematic. Affected is some unknown functionality of the component Kernel. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on availability. CVE summarizes:

The kernel in Apple iOS before 8.3, Apple OS X before 10.10.3, and Apple TV before 7.2 allows attackers to cause a denial of service (out-of-bounds memory access) or obtain sensitive memory-content information via a crafted app.

The weakness was disclosed 05/19/2015 by Maxime Villard (lokihardt@ASRT) with m00nbsd as HT204870 as confirmed advisory (Website). The advisory is available at This vulnerability is traded as CVE-2015-1100 since 01/16/2015. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Maxime Villard in ANSI C and been published before and not just after the advisory. The exploit is shared for download at It is declared as proof-of-concept. As 0-day the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 82712 (Apple TV < 7.2 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Misc..
