A vulnerability in the Linux kernel has been discovered that affects all Linux kernels.
While we are in the course of preparing a new OVH kernel based on the long-term 4.4 series, we cannot update our public default kernels to 4.4 just yet because of several issues, mostly due to hardware compatibility, that need to be resolved.
We have for now instead decided to recompile the currently used 3.14.32 kernel (that already includes patches for prior vulnerabilities) with a backported fix to this issue.
This patched kernel is available on our ftp server: ftp://ftp.ovh.net/made-in-ovh/bzImage/latest-production/ It has also been rolled out on our reinstallation system for dedicated servers (if no other kernel is chosen during reinstallation launch) as well as on our netboot services.
We strongly encourage all users on 3.14.32 kernels to update their system. If uncertain on which patchlevel you are, please refer to the output of \"uname -a\" - the fixed kernels have recompilation number 9 and todays date, for example:
# uname -a
