Google has plans to release the mid-month security updates as they have discovered an exploit that could be a source of harm to some Nexus devices mainly the Nexus 5 and Nexus 6.
Google found this issue after using an un-patched local elevation of privilege exposure in the critical Linux Kernel by rooting application. But Google didn’t mention the name of the rooting application. The issue found that a malicious application would have an easy chance to deliver a negative effect of the code within the software. In order to fix that issue, you have to re-flash the whole operating system.
However, the bug cannot affect the OS easily as Google protect you from such apps in Google play Store by verifying apps to keep the phones away from external threats. The only way to get affected is if you manually install the rooting app.
There are ways to stay safe in multiple layers of security but if you have a trouble in your side then you should be waiting for the update coming within few days. In our side, we can tell you that the android partners are already been informed for the issue and you can see new information at AOSP repository. You may be experiencing a random update coming to your phone just in a few days as Google is gradually updating the stuff related to the security for your phone.
Google has also informed the android partners on this issue and has updated the new information on AOSP repository.
“To provide a final layer of defense for this issue, partners were provided with a patch for this issue on March 16, 2016. Nexus updates are being created and will be released within a few days. Source code patches for this issue have been released to the Android Open Source Project (AOSP) repository.”
