Canonical announced that a couple of vulnerabilities had been found in the Linux kernel packages, this time affecting the OMAP4 kernel of the Ubuntu 11.10 (Oneiric Ocelot) operating system.

The CVE-2012-4530 Linux kernel vulnerabilities affected Ubuntu 11.10 (Oneiric Ocelot) OMAP4.

According to Canonical, the system could be made to leak data on the kernel stack. A flaw has been discovered in the Linux kernel's handling of script execution when module loading is enabled. A local attacker could exploit this flaw to cause a leak of kernel stack contents.

A complete description of the vulnerabilities can be found in the Ubuntu Security Notice.

The security flaws can be fixed if you upgrade your system to the linux-image-3.0.0-1220-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.
