My ubuntu server 12.04.4 LTS is running kernel 3.5.0-54.81~precise1. I need to patch the kernel to avoid the Dirty Cow vulnerability. By researching the forums I found that the release that fixes the bug in 12.04 is 3.2.0-113.155
Obviously 3.2.0-113.155 was released long after 3.5.0-54.81~precise1, however, because of being a lower version, the OS boots to the 3.5 kernel.
My question is if 3.5.0-54.81~precise1 is affected by the bug and I need to change it to 3.2.0-113.155 or there is a 3.5 release that fixes the bug.
Kind regards, Pavlos Polianidis
