Apple Watch up to 1.0.2 Kernel Kernel Memory information disclosure

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Apple Watch up to 1.0.2 (Smartwatch Operating System). It has been classified as problematic. This affects an unknown code of the component Kernel. The manipulation with an unknown input leads to a information disclosure vulnerability (Kernel Memory). CWE is classifying the issue as CWE-200. This is going to have an impact on confidentiality.

The weakness was disclosed 09/23/2015 by Filippo Bigarella (beist) as HT205213 as confirmed advisory (Website).
