By now you might have noticed that your BlackBerry PlayBook received an OS update. The latest update (version 18.104.22.1682) fixes a known vulnerability with Adobe’s Flash Player. Everyone should have received a notification about the update by now, but in case you haven’t go into your settings, system updates, and check now.
Earlier this week, Adobe® issued an update for Adobe® Flash® Player, which addresses an issue that affects all systems running Flash.
As such, a new version (version 22.214.171.1242) of the BlackBerry Tablet OS will soon be available to all BlackBerry® PlayBook™ tablet users, which contains an updated version of Adobe Flash Player within it. This free update can be downloaded over-the-air from your BlackBerry PlayBook.
While there are no known reports of any BlackBerry PlayBook users being affected by the Adobe Flash issue, we encourage all BlackBerry PlayBook users to update to this newest version of the BlackBerry Tablet OS.
