Samsung also expressed their opinion that this exploit will not offer too much of a threat, as the hacker will need to be on an unsecured network with your smartphone in the first place, not to mention that Samsung’s Knox security software does come with kernel protection in order to prevent malicious code from being executed, but having said that, this is not one backdoor that any company can and should ignore, but rather, it ought to be patched ASAP.
In order to ensure that your Samsung device is primed to receive the security update, go to Settings > Lock Screen and Security > Other Security Settings > Security policy updates, make sure the Automatic Updates option is toggled, and while you are at it, might as well click Check for updates in order to be sure that any new security policy updates which pop up will be downloaded.
