Detailsinfo

A vulnerability was found in Google Android (Smartphone Operating System) (unknown version). It has been rated as problematic. This issue affects an unknown code block of the component Linux Kernel. The manipulation with an unknown input leads to a information disclosure vulnerability (Kernel Memory). Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. The summary by CVE is:

In Android before 2017-08-05 on Qualcomm MSM, Firefox OS for MSM, QRD Android, and all Android releases from CAF using the Linux kernel, if kernel memory address is passed from userspace through iris_vidioc_s_ext_ctrls ioctl, it will print kernel address data. A user could set it to an arbitrary kernel address, hence information disclosure (for kernel) could occur.

The bug was discovered 08/05/2017. The weakness was presented 03/30/2018 by Security Team with Qihoo 360 (Website). The advisory is shared at source.android.com. The identification of this vulnerability is CVE-2017-9681 since 06/15/2017. The exploitation is known to be easy. The attack may be initiated remotely. The requirement for exploitation is a simple authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 237 days. During that time the estimated underground price was around $25k-$100k.

Applying a patch is able to eliminate this problem.
