USN-1997-1: Linux kernel (OMAP4) vulnerability

22 October 2013

The system could be made to expose sensitive information to a local user.

Releases

Packages

Details

Dan Carpenter discovered an information leak in the HP Smart Array and
Compaq SMART2 disk-array driver in the Linux kernel. A local user could
exploit this flaw to obtain sensitive information from kernel memory.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.10

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.
