    The Exploit source : 1
    The Exploit source : 2

    user alephazin has discovered a vulnerability in Exynos processors version 4210 and 4412 that essentially allows any Android app to access and control the whole device :

    That means - A newly written exploit could be incorporated into any application that would have root-level permissions on a device. Risking private data and opening root permissions.

    Some of the devices that could be affected are

    • Samsung Galaxy S2 GT-I9100
    • Samsung Galaxy S3 GT-I9300
    • Samsung Galaxy S3 LTE GT-I9305
    • Samsung Galaxy Note GT-N7000
    • Samsung Galaxy Note 2 GT-N7100
    • Verizon Galaxy Note 2 SCH-I605 (with locked bootloaders)
    • Samsung Galaxy Note 10.1 GT-N8000
    • Samsung Galaxy Note 10.1 GT-N8010.

    Sr. dev on XDA Chainfire has already created app ExynosAbuse to gain root privileges and install the latest release of SuperSU “on any Exynos4-based device.”

    Sort of ... Actual fix is still awaited.
    The workaround by Chainfire has a downside - it may leave the camera app unusable :(

    Official fix : Samsung should roll out that soon as there is a large percentage of users who remain on stock.
    Unofficial : Sure someone at XDA might be working on that.

    In any case.. its and easy way to root and (I suppose) avoid increasing the counter.
