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.

Detailsinfo

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. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. The summary by CVE is:

XNU in the kernel in Apple iOS before 9 does not properly initialize an unspecified data structure, which allows local users to obtain sensitive memory-layout information via unknown vectors.

The weakness was disclosed 09/23/2015 by Filippo Bigarella (beist) as HT205213 as confirmed advisory (Website). The advisory is shared at support.apple.com. This vulnerability is uniquely identified as CVE-2015-5842 since 08/06/2015. The exploitability is told to be difficult. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1592 for this issue. The advisory points out:

An issue existed in XNU that led to the disclosure of kernel memory. This was addressed through improved initialization of kernel memory structures.

The vulnerability scanner Nessus provides a plugin with the ID 86270 (Mac OS X < 10.11 Multiple Vulnerabilities (GHOST)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 370192 (Apple Mac OS X v10.11 Not Installed (APPLE-SA-2015-09-30-3)).

Upgrading to version 2 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (86270), SecurityFocus (BID 76764†) and Vulnerability Center (SBV-53149†). The entries VDB-9015, VDB-68413, VDB-74127 and VDB-77828 are pretty similar. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
