A vulnerability classified as problematic has been found in Apple Mac OS X up to 10.11.3 (Operating System). Affected is an unknown code block of the component Kernel. The manipulation with an unknown input leads to a memory corruption vulnerability (Memory). 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. CVE summarizes:

The kernel in Apple iOS before 9.3 and OS X before 10.11.4 allows attackers to obtain sensitive memory-layout information or cause a denial of service (out-of-bounds read) via a crafted app.

The weakness was published 03/21/2016 as HT206167 as confirmed advisory (Website). The advisory is available at support.apple.com. This vulnerability is traded as CVE-2016-1758 since 01/12/2016. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. Technical details are unknown but a public exploit is available. The advisory points out:

An out-of-bounds read issue existed that led to the disclosure of kernel memory. This was addressed through improved input validation.

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 90096 (Mac OS X 10.11.x < 10.11.4 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 and running in the context c.
