Pinned and security

I use the driver 260.19.26 from last CUDA Toolkit 3.2 on a linux 64-bit machine.
I have noticed that allocating using pinned memory, driver gives to unprivileged users(me for example) uninitialized memory pages.
This might be a security bug, and might be in contrast with security/privacy policies of linux kernel.

What do you think about it, is this right?
