A vulnerability was found in Apple iOS up to 9.0 (Smartphone Operating System). It has been classified as critical. Affected is some unknown processing 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 confidentiality, integrity, and availability. CVE summarizes:

The kernel in Apple iOS before 9.1 and OS X before 10.11.1 does not initialize an unspecified data structure, which allows remote attackers to execute arbitrary code via vectors involving an unknown network-connectivity requirement.

The weakness was released 10/21/2015 by Xiaofeng Zheng (Brainy Code Scanner) with m00nbsd as HT205370 as confirmed advisory (Website). The advisory is shared for download at support.apple.com. This vulnerability is traded as CVE-2015-6988 since 09/16/2015. The exploitability is told to be difficult. Access to the local network is required for this attack to succeed. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 06/24/2022). It is expected to see the exploit prices for this product increasing in the near future. The advisory points out:

An uninitialized memory issue existed in the kernel. This issue was addressed through improved memory initialization.

The vulnerability scanner Nessus provides a plugin with the ID 86654 (Mac OS X < 10.11.1 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks.

Upgrading to version 9.1 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.
