During the September Patch Cycle, Google remedied 50 vulnerabilities in Android, including eleven that have been identified as serious. Through serious leaks, an attacker can execute arbitrary code through a modified file within the context of a privileged process.
The serious vulnerabilities are present in the Android system, the Media framework and parts of Qualcomm. Through the remaining security vulnerabilities, an attacker could cause a denial of service, steal information or increase his rights to the system. A large part of the Android vulnerabilities patched this month are in the “closed-source” components of Qualcomm.
For owners of Pixel devices, Google has released a separate security bulletin to patch 15 security leaks. None of the vulnerabilities has been labeled as serious. The vulnerabilities are present in NFC, the WLAN HOST, audio and kernel.
Google works with so-called patch levels, with a date representing the patch level. Devices that receive the September updates will have ‘2018-09-01’ or ‘2018-09-05’ as patch level. Manufacturers who want their devices to have this patch level should in this case add all updates to the September Android bulletin to their own updates, and then roll them out among their users. However, it is not mandatory to include the updates for the additional vulnerabilities listed in the Pixel / Nexus bulletin.
Google has now made the updates available for Nexus and Pixel devices. Manufacturers of Android devices according to Google at least a month ago about the now repaired vulnerabilities informed and have in that time updates can develop. However, that does not mean that all Android devices will receive these updates. Some devices are no longer supported with updates from the manufacturer or the manufacturer releases the updates at a later time. Recently, it became known that 1 billion Android devices did not receive any security updates last year.

Note: If there is more than one download option, that likely means that you need to download and install the Bug Fix Update for your smartphone or tablet device before you can actually update to 6.0.1 Marshmallow.
Step 1:Before you go trying to update your device, you should check which version of Android you are running. You might already be on the latest version. It's easy to check so follow this guide up to step four. This screen will have a section called 'Android version'. If it doesn't, click 'Software information' to find out.
Step 2:Scroll down the Settings menu and click on 'About Phone' or 'About Tablet'. If you have a tabbed settings menu then this will appear in the 'general' section.
Refer to Android developer page to choose which version of Android your phone or tablet is running. I.e, 4.0.4 corresponds to Ice Cream Sandwich, an old version of Android that was released in 2013.
Step 3:Note: Your phone or tablet may require a Wi-Fi connection to search for an update. We suggest you to download the software Droid Over Wi-Fi because the file size can be large.
Choose and click the "Software Update" option. Next it will search available update for your phone or tablet. If update is available, you will be asked if you want to install it. Select "yes" and it will install the new operating system in your device. If you want to install it later, you can download the Android 6.0.1 Marshmallow file first.
