| Message-ID | <tkFR7-6IY-5@gated-at.bofh.it> |
Hello, can someone please help me find out which kernel version (and sub-version) I have? Don't scould, I have done the search on Google and in the Debian documentation on how to find one's kernel version, but I am confused by the results: $ uname -v #1 SMP Debian 3.16.7-ckt25-2+deb8u3 (2016-07-02) $ uname -r 3.16.0-4-686-pae $ apt-cache show linux-image-686-pae Package: linux-image-686-pae Source: linux-latest (63) Version: 3.16+63 [...] So is the kernel version of my system 3.16.7, 3.16.0 or 3.16.63? (Backgroud: I wanted to find out whether the Dirty COW bug was fixed in my system. According to https://en.wikipedia.org/wiki/Dirty_COW#Remedies_and_recourse, it is fixed from version 3.16.36-1+deb8u2 onwards.) Kind greetings, Georg

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. No, not yet. > According to > https://en.wikipedia.org/wiki/Dirty_COW#Remedies_and_recourse, it is > fixed from version 3.16.36-1+deb8u2 onwards.) You are running a kernel that is older than this. 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. (Best not to rely 100% on wikipedia without verification.)
