Canonical announced a few minutes ago (March 27th), in a security notice, that a new kernel upgrade for its Ubuntu 11.10 (Oneiric Ocelot) operating system is available. The update is here to fix seven security vulnerabilities discovered in the Linux kernel packages by various developers. The flaws are related to VLAN and be2net drivers, the SG_IO ioctl command, the KVM subsystem, the CIFS filesystem, and the cgroups subset.
These are the kernel vulnerabilities found in the kernel packages:
CVE-2011-3347,
CVE-2011-4127,
CVE-2011-4347,
CVE-2012-0045,
CVE-2012-1090,
CVE-2012-1097, and
CVE-2012-1146.
As usual, you can click on each one to see how it affects your system, or go

The security flaws can be fixed if you upgrade your system(s) to the
