The vulnerability allowed an attacker, just with physical access to your device and a computer at hand, to boot any kernel image that they want without even needing to have USB debugging left on. The vulnerability was discovered by Edge Security, and at the time, OnePlus had said it would fix the issue in an upcoming software update. The latest version rolling out isn't so different from the rest, but the new flagship isn't the only OnePlus device on the receiving end of new software updates. However, the company has said that it will roll-out OxygenOS 5.1.8 update in India next week that will contain fix for the issues reported as well as all the features that are included in OxygenOS 5.1.7 update.
While it's appeasing that the serious Bootloader vulnerability and Scheduled DND related issues have been taken care of in OxygenOS 5.1.7, OnePlus 6 users in India are now out of luck as they will have to wait for OxygenOS 5.1.8, which is set to roll out next week. Did you face any issues with OxygenOS 5.1.6 update?
Instead, the company is working on fixing the problem and has promised to release in the OxygenOS v5.1.8 in the coming week.
Meanwhile, OnePlus 6 owners in the rest of world are advised to update their device to the OxygenOS 5.1.7 as early as possible.
Besides that, there are other few changes that come with the update as well.
This update should be rolling out now to all OnePlus 6 users except in India, where some localized problems have OnePlus holding the update back.
