Descriptions

An issue was discovered in certain Apple products. iOS before 10.2 is affected. macOS before 10.12.2 is affected. watchOS before 3.1.3 is affected. The issue involves the "IOKit" component. It allows local users to obtain sensitive kernel memory-layout information via unspecified vectors.

Se ha descubierto un problema en ciertos productos Apple. iOS en versiones anteriores a 10.2 está afectado. macOS en versiones anteriores a 10.12.2 está afectado. watchOS en versiones anteriores a 3.1.3 está afectado. El problema involucra al componente "IOKit". Esto permite a usuarios locales obtener información sensible de la disposición de la memoria del kernel a través de vectores no especificados.

This vulnerability allows local attackers to disclose sensitive information on vulnerable installations of Apple macOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within IOReportUserClient. The process does not properly validate user-supplied data which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges under the context of the kernel.
