On July 9th, Canonical announced that a vulnerability was found in the Linux kernel packages, this time affecting the OMAP4 kernel of the Ubuntu 11.10 (Oneiric Ocelot) operating system.
The CVE-2012-2375 Linux kernel vulnerability affects Ubuntu 11.10 (Oneiric Ocelot) OMAP4. As usual, you can click on the link to see how it affects your system, or go here for in-depth descriptions, as it affects other operating systems as well.
The security flaws can be fixed if you upgrade your system to the linux-image-3.0.0-1212-omap4 package. Don't forget to reboot your computer after the upgrade!
ATTENTION: Due to an unavoidable ABI change, the kernel packages have a new version number, which will force you to reinstall and recompile all third-party kernel modules you might have installed. Moreover, if you use the linux-restricted-modules package, you have to update it as well to get modules that work with the new Linux kernel version.
