It's the same as uname -a, just in pieces. > So is the kernel version of my system 3.16.7, 3.16.0 or 3.16.63? Yes. Two of the above. You are running Debian kernel 3.16.7-ckt25-2+deb8u3 which is compatible with the kernel ABI used in Debian kernel *package* 3.16.0-4-686-pae. > (Backgroud: I wanted to find out whether the Dirty COW bug was fixed in > my system.

If you have installed a newer kernel, you have not yet rebooted into it. https://security-tracker.debian.org/tracker/CVE-2016-5195 confirms that you want 3.16.36-1+deb8u2.
