Re: Does Blackberry 10 have Kernel Address Space Layout Randomisation?

Don't forget that BB10 is built on QNX so any questions like these just google for 'QNX +xxx'.

According to these it does...

Re: Does Blackberry 10 have Kernel Address Space Layout Randomisation?

Well, it's something we could have turned off for BB10 if we wanted. BB10 is based on QNX Neutrio, but Neutrio is extremely flexible so it can do a lot of things, so just because it's avaiable in QNX doesn't necessarily mean it's in BB10.

 

Of course, we definitely left it on in this case, with a host of other security measures.

I did think about mentioning BlackBerry could have turned this off but I half remembered reading somewhere that it was in there but couldn't find the document, and I couldn't see why you would have.

Thanks for the link.

Yeah, it was definitely a fair assumption, just wanted to make sure other people reading this didn't get the wrong idea and apply it to other features we may not have included.
