Ubuntu 1422-1: Linux kernel vulnerabilities
Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 11.04: linux-image-2.6.38-14-generic 2.6.38-14.58 linux-image-2.6.38-14-generic-pae 2.6.38-14.58 linux-image-2.6.38-14-omap 2.6.38-14.58 linux-image-2.6.38-14-powerpc 2.6.38-14.58 linux-image-2.6.38-14-powerpc-smp 2.6.38-14.58 linux-image-2.6.38-14-powerpc64-smp 2.6.38-14.58 linux-image-2.6.38-14-server 2.6.38-14.58 linux-image-2.6.38-14-versatile 2.6.38-14.58 linux-image-2.6.38-14-virtual 2.6.38-14.58 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
