Samsung released a new firmware update for the Galaxy A5 (2016) late last month which brought the November security patch. A new update weighing in at 128MB is now being rolled out for the Galaxy A5 (2016) in a handful of markets across the globe. The changelog mentions that the latest update brings a patch for a “critical flaw,” but it doesn't explain what this flaw is.
You would be wrong to assume that this update includes the December security patch because it doesn't. Samsung hasn't even detailed the latest Security Maintenance Release and it hasn't made its way to any of the company's devices as yet. This update retains the November security patch and basically just takes care of the “critical flaw” mentioned in passing in the changelog.
This update has already been rolled out across a handful of countries in Europe and Africa. The rapid rollout suggests that the flaw might have been quite serious which prompted Samsung to quickly send out a new update for this device that doesn't do much else than fixing this flaw. It's pertinent to mention here that a similar update was released in the first week of November as well to patch another “critical flaw.”
